Diagonal Seam Tape™

How to use Diagonal Seam Tape while sewing

Back in stock in my shop here!  

I shared a peek at this last week, but I thought it probably deserves it’s own post since it took me forever to develop!  

I’ve been using painters tape as a guide on my machine for years…I even wrote a post about it 9 years ago here.   I usually use it for sewing diagonal seams instead of marking lines, but I also use it for making HST’s.  There are lasers, or plastic seam guides you can buy and attach to your machine with adhesives, but I found them bulky and a pain to use.

So I decided to make my own tape that is pretty, functional, and easy to use.  

Diagonal Seam Tape™ is washi tape that is tough but thin, and easily removable.   I made a long web page devoted to it here:

It’s placed in front of the feed dogs of the machine, and the red line is the stitching line, placed in front of the needle.  The black lines are just a perk, they represent a 1/4″ seam allowance and are helpful when making HST’s, keeping strips straight while strip piecing, or even helping a beginner learn to piece.  

Mostly you’ll use the red line for making diagonal seams without marking a pencil line on your square, like when making a snowball block:

Or you can using it when making flying geese units:

You can use it anywhere in a pattern that tells you to “mark a diagonal line”, or anywhere you need to sew a diagonal seam.   In patterns with multiple diagonal seams like Chickens, Bats, Trellis, or Shimmer…using tape is what saves me the most time!

I could go on and on…but ALL the info and more is in the web page for the tape you can read through here.

You can find Diagonal Seam Tape in my shop here.  

I’m thrilled with how it turned out after months of thinking about it and working out the details of printing (long story short… it’s a big fat pain and costly to have something so precise printed on tape!).   After using it on my own machines for a couple of months I can’t imagine not having it.   I don’t know if I’ll re-print it again, so I hoarded enough to last me at least until I’m 90… or until I get a sewing machine with a fancy laser guide built in (all machines should have them!).

    This tape looks like a great invention ! Painters tape always comes unstuck at one edge and is really hard to line up ! I have an older machine, and I bought a top rated laser guide for it and mounted it as per the instructions. It cost me almost$ 70. including shipping. It constantly moves out of alignment, making it useless ! Your tape looks like a much better option !

      Thanks! I wondered about trying a laser but I’d heard they were hard to get in the right position. So for now it’s tape for me!

    I have always used painters tape or regular washi tape, but I love this with the lines. Great idea!

  3. Sheila August 23, 2019 at 6:36 am #

    Great idea! Thanks for sharing it with us.

    This is great! I also have a Juki and that 1/4 line is so wrong! (but I love my Juki for everything else, except the needle threader). I will be ordering some tape as soon as I think about what pattern(s) to order at the same time. This is going to sell fast…I hope you have some mailing help!!

    • Allison August 23, 2019 at 5:40 pm #

      I do need some mailing help! ;) The Juki line drives me crazy on my machine too…it is SO wrong!

      • Mary C August 26, 2019 at 6:45 am #

        yes, I always wonder how they can engineer such a good machine but not know what a quarter inch is! Obviously I waited too long to order. I will watch for your restock. I thought too long TWICE on Saturday! — missed some of the new National Park small poster fabric from my favorite shop too !

      • Allison August 27, 2019 at 10:20 am #

        Oh darn! I will get more in soon…hopefully in the next ten days or so!

    • Gay August 24, 2019 at 6:14 am #

      I would love to buy some of your seam tape when it’s back in stock. How do I do that?

      • Allison August 25, 2019 at 12:09 pm #

        I will post (or you can email me and I’ll email you back) when I restock, and hopefully I’ll have it in stock longer this time!

      • Rosalyn Schultze August 28, 2019 at 7:24 am #

        Please put me on the ‘WAIT’ list for your tape. Thanks much!

  5. Joan Pekrul August 23, 2019 at 8:39 am #

    You are a genius!!! Thank you so much for inventing, creating this tape!! I’ve ordered 2 and I can’t hardly wait to get them!! I will be ordering more for Christmas presents!! You are going to be very busy mailing all your orders.

    • Allison August 23, 2019 at 5:40 pm #

      Haha thanks Joan! I know what I’m doing this weekend…shipping! ;)

  6. Nancy Angerer August 23, 2019 at 9:05 am #

    You should sell these — I would at least buy one to try. They look like they would be something that I would find really helpful and would rebuy.

    • Allison August 23, 2019 at 5:39 pm #

      Thanks Nancy, I’m going to reprint them and have them back to sell soon.

  7. Bettina Kesteloot August 23, 2019 at 9:06 am #

    Fabulous idea. I just ordered a roll. Thank you for your creativity.

  8. Terrie D. August 23, 2019 at 1:18 pm #

    What an awesome idea! This tap me looks perfect. :)

  9. Brenda Reinhardt August 23, 2019 at 3:14 pm #

    Do you not ship to Canada?? I can not get my order to work. Like this idea of the tape and love your patterns – Bats are so cute!!

    • Allison August 23, 2019 at 5:37 pm #

      Hi Brenda! Not the tape no…because shipping is $10.50 a roll! It just qualifies as a package even though it’s still in a thick envelope. I’m trying to find a solution!

    • Jane Lowas September 5, 2019 at 3:27 pm #

      Hello can I be put on ur notification list as well for the tape? Thank you

  10. Megan August 23, 2019 at 3:25 pm #

    Oh how very very disappointing. I rushed straight to your shop to buy some and no shipping to my destination. I won’t comment further, just to say it is not unusual but nonetheless disappointing.

    • Allison August 23, 2019 at 5:34 pm #

      I’m sorry Megan! Because it just barely qualifies as a package, the shipping is crazy! $10 just to Canada, and even more anywhere else. I’m trying to figure out a better way to ship them so stay tuned!

  11. Cindy Derr August 23, 2019 at 4:39 pm #

    Just received my order yesterday, and I love it! So glad you’re producing this (and grateful you are re-stocking!)

    • Allison August 23, 2019 at 5:34 pm #

      I’m glad you like it Cindy!

  12. Judy Dobbins August 24, 2019 at 9:02 am #

    Brilliant idea Allison! Will keep my eye open for when you restock!

  13. Brenda Reinhardt August 24, 2019 at 9:41 am #

    Brenda here again! I am willing to pay that $10 fee!! lol Right now, I am good at guessing and sewing with my fingers crossed, so that is why I think this tape mght be a better idea!! I have just bought another sytem for this but it has not shown up yet in the mail, and I have misplaced my original one a long time ago. Let me know when you are re-stocked and lets figure it out. I was thinking of buying 3 – one for me and the others for friends. Would that help you feel better about that $10? Or (gasp!!) would it make that s/h even more??? lol

    • Allison August 25, 2019 at 12:08 pm #

      Okay Brenda! I will post when I restock or you can email me and I will send you an email when I restock. When I restock I’m going to open it up to Canada shipping, and I think I found a more affordable option too that at least saves a few dollars! The shipping is the same whether you buy 1 or 10…which is why it’s so silly to send one tiny tape in the mail for $10!

      Have a great day! -Allison

  14. Nettie August 25, 2019 at 6:22 am #

    This is brilliant! Can’t wait for the restock!

  15. Kim August 25, 2019 at 4:33 pm #

    What a brilliant idea!!! I want some for me and for friends for Christmas. Let me know when you are restocked!

    • Allison August 27, 2019 at 10:21 am #

      Thanks Kim! I’m hoping to have more in the next 10 days or so! I’ll post when I do!

  16. Fussell August 26, 2019 at 8:30 am #

    I’m definitely interested! I’ve been looking at the Harbor Freight laser that seems very popular but I am bad about bumping things so this looks much easier! I can also grab a couple patterns to go with! ;)

    • Allison August 27, 2019 at 10:19 am #

      I would do the same with the laser!

  17. 57andfemale August 26, 2019 at 12:57 pm #

    I spent many frustrating hours trying to make something exactly like this. I will order as soon as you re-print.

    • Allison August 27, 2019 at 10:19 am #

      Haha me too! That’s why I made it! :) I’m hoping to have more within ten days or so!

  18. Trish August 28, 2019 at 7:38 am #

    Looking forward to ordering a couple of rolls, early xmas shopping, and a pattern when the tape is back in stock.

  19. hotmail email login August 29, 2019 at 3:18 am #

    Wow! I didn’t know this simple addition can be this helpful! Thank you for sharing!!

  20. Margaret Andrews August 29, 2019 at 5:15 pm #

    I just received your tape…what a time saver! First time I used it I goofed, but ripped it out and relooked at the instructions and the second time was the charm. So easy, if you follow the directions. I am making the Chicken blocks and it makes sewing the small diagonal pieces so simple. Thank you. I will share the news of your tape with others in my guild. Hope they will like it as much as I do…..but they will have to wait to order…I didn’t, lucky me.

  21. pam September 3, 2019 at 5:29 am #

    I also have a Juki and I do not use the 1/4 inch line. And you are right about the needle threader. I used it once and I have never gotten it to work again. I’ll be watching for this!

  22. Amy Cotham September 9, 2019 at 12:32 pm #

    OMG, OMG, OMG!!! I’ve made my own diagonal tape for awhile and now to have it at my fingertips is so luxurious. Please let me know when you have them in stock again. I will be stocking up. Thank you!!

    • Allison September 9, 2019 at 9:47 pm #

      I just restocked today! They are in my shop (link is in the post). And yes, I will be selling them wholesale, they can email me at cluckclucksew@gmail.com if they want them. Thanks! -Allison

  23. Amy Cotham September 9, 2019 at 12:36 pm #

    Will you be selling them wholesale also? My local quilt shop needs these.

  24. Joan Pekrul September 10, 2019 at 11:25 am #

    OMG, I love, Love my tape!!! I’m so glad I bought 2 rolls. You are the Woman for coming up with this idea!! Thank you!!!

    • Allison September 10, 2019 at 11:44 am #

      Thanks Joan!! I hope you love it!!

  25. bogeywogeybiker September 14, 2019 at 2:55 pm #

    love it I am going to share it with my fellow quilt club members

  26. Irene September 28, 2019 at 12:39 pm #

    I have a order Paid by —-It does not taking it Would like The Tape and the Trellis Pattern

  27. froggle13 October 30, 2019 at 7:57 am #

    THANK YOU so much for your lightening fast service!
    I think this tape is going to revolutionize my sewing.

  28. Katharine Burge November 13, 2019 at 9:42 am #

    We got our puppy a Nylabone. They are expensive, but almost indestructible. After five and a half years, it is still her favorite toy.

  29. Rain May 18, 2020 at 9:38 am #

    Can’t say enough about this tape! Sewing multitudes of snowballs, and being doubly careful, I had marked my corner squares in conjunction with using my Diagonal Seam Tape. So many times the tape was way more accurate then the marked line! No more marking for me. Every quilter NEEDS this tape.

    • Allison May 20, 2020 at 8:48 pm #

      That makes me so happy that you love it and it worked for you!! Thank you!
