Triangle Corner Trick

I was piecing these blocks with triangle corners (like the corners in this block) yesterday and thought I would share a quick trick. Usually a pattern (including my own) will recommend drawing a pencil line from corner to corner on the wrong side, and sewing along the line. Like this one:
But since I’m a hurried sewer and drawing little lines on 160 squares doesn’t sound like super fun, this is what I do instead:
Place a piece of tape so that edge is in line with the needle of your machine.
When you are sewing on your squares, start in one corner, and keep the opposite corner on that tape edge to keep the seam line straight.
When your done you’ll have a nice straight line from corner to corner, without having to draw gagillions of little pencil lines. Keep in mind though that the smaller the square the easier it is, it might be a little harder to keep a perfectly straight line with bigger squares.
After trimming and pressing the corner should look like this:
Tricky huh? I learned this from my Mom. I always wondered why she had painters tape stuck to the front of her machine….now we know.

    Mind blown. Thank you!

    I love you. I seriously owe you like a child or something. I was facing doing this for way too many blocks to fathom and was dreading the heck out of it.

    You're so clever! Thank you.

  15. Mary October 25, 2010 at 6:14 pm #

    Brilliant! Thanks so much!

    Great tip! The quilt shop where I first learned how to quilt recommended that if we were having trouble keeping a 1/4 inch SA. Works great for these triangles, since I agree, who wants to draw all those lines! We want to get to the piecing and quilting part, right?!

  17. "Lois Grebowski" October 25, 2010 at 8:41 pm #

    Painter's tape is my best sewing friend (besides my seam ripper). I love it. great idea for keeping it straight. Thanks for sharing!

    Oh how I wish you would've posted this 9 months ago… when I was drawing pencil lines on 123948102349824619286 triangles! Great post, I will definitely use this shortcut!!!

  21. Emily Elizabeth October 25, 2010 at 10:54 pm #

    Wonderful wonderful tip. Thanks for passing it along!

    Nice idea and once you set it up, it saves on the tracing step.

    Well, how about that. What a great idea! Thanks for sharing!!

  25. Bec Clarke October 26, 2010 at 5:23 am #

    Oh I just did a million little half square triangles for pinwheels. I will be using this next time.

  26. mummastimetocreate October 26, 2010 at 6:44 am #

    Yay thanks for this tip!! I'm so lazy when it comes to pinning and drawing, so this is a great tip for me! Painters tape is also good if you don't like pinning – I just stick it to one corner to stop the pieces moving. It loses it's stick reasonably quickly, but you only need a tiny bit and it's so much faster (and less hazardous LOL…) than pinning.

  27. Kate October 26, 2010 at 10:51 am #

    Thanks for the fantastic tip! Sounds like you had a very clever mum.

  28. Linda October 26, 2010 at 11:43 am #

    BRILLIANT!

    Great tip! thanks so much!

  32. Ronda October 26, 2010 at 3:44 pm #

    I learned this in a quilting class. Now all my machines have tape on them. This is a great idea and I appreciate you reminding us of this. It simplifies and that is just what all of us quilters need.

  33. Diane October 26, 2010 at 6:01 pm #

    Wow! Neat trick…. I hate drawing all those lines.

  34. Joanna October 26, 2010 at 7:49 pm #

    Great idea. Thanks to you and your mom. I hate the line drawing.

  35. Jantine October 26, 2010 at 8:55 pm #

    Wow, thanks,you just got me over a hurdle 😉

  38. di October 27, 2010 at 3:08 am #

    Oh wow! Thanks for sharing this with us! I have a quilt that I want to make that makes it's blocks like that and now i'm really wishing that I had one of those extension tables for my machine. lol

  39. Linda October 28, 2010 at 10:59 pm #

    You and your mom are SO CLEVER! Thanks a bunch for this tip. PS There is a cream stick in Amishland with your name on it and a donkey or two missing you!

  40. Belinda October 29, 2010 at 12:13 pm #

    If you also sew another line 1/2" away from the first (out towards the corner)& cut between the sewing, you get a bonus 1/2 sq triangle :)

  41. Karen November 2, 2010 at 9:00 am #

    I just love simple but brilliant ideas like this!

  42. Cowgirl in the City November 2, 2010 at 7:48 pm #

    Awesome! I wish I had thought of that last weekend when I was grumbling at all my little triangles! Thanks for the tip.

  43. Fabric Warrior November 5, 2010 at 3:10 am #

    I tried this trick yesterday, and it worked wonderfully. I cannot offer enough thanks!! It saved me SO much time making half-square triangles.

  44. eileensideways November 6, 2010 at 3:15 am #

    how do u cope with the machine eating the corners?

  45. Diane November 7, 2010 at 10:39 pm #

    I was getting ready to start a quilt with these little triangles and said 'wait! I remember something about a trick to di these…. now where did I see that" Thanks !!!

  46. bethanndodd July 6, 2011 at 4:12 pm #

    Loving this tip! Especially since I will be making one of those 4th of July star quilts…thanks! Smiles~Beth

  47. Elle September 14, 2011 at 6:53 pm #

    I love this trick! My addition to it is that I usually now will sew another seam about 3/8" away from the first one, but them apart with a very scant 1/4 inch seam, and then I save all those list squares to put into charity quilts/mini-quilts/other projects (especially if I'm chain piecing, since I can just run them all through the machine in line again, using my existing seam line as my guide (and my 1/4 inch foot is a little wider on the left, so it works pretty perfectly.) Probably silly, but I read a blog entry about getting extra charity quilts from scraps, and despite the fact that I have too much fabric and need to use it up, I've become a bit obsessed with reducing waste. Anyway, I thought I'd share (and at the same time thank you for this great tip – it has made my sewing speed up considerably)!

  48. Tora´s Vintage Dream October 17, 2011 at 9:08 pm #

    This sounds so easy I´m going to use this tip when I will sew my corners on a lot of snowball blocks, thanks for the tip :)

  49. Just Carol November 6, 2011 at 3:14 pm #

    So simple–what a great idea! I hate drawing those lines. Thanks!

  50. Susan November 22, 2011 at 1:31 pm #

    This is the most life changing thing to have found on pinterest today. How is it that I didn't know this while drawing all those stinking lines for the Swoon quilt?! :) thanks for sharing!!

  54. Goldogmom September 7, 2012 at 5:13 am #

    a great tip. Can you share what you use these blocks for? Ive made HST but like the idea of the different sizes of these two pieces, making a block. Do you have a pattern for using them?

  58. Julie Bagamary March 4, 2013 at 2:11 pm #

    GREAT tip! I passed along to my friend who does more precision piece that I do.

    Thanks for the tip, I will have to try this out….

  61. Cynthia Oxford-Fishman January 30, 2014 at 1:47 pm #

    I am new at quilting and I am right now gathering a lot of information/tips as to how to make quilting fun instead of work. I want to thank you for this tip. I hope you do not mind me asking this question, if I folded my square in half, finger press it or iron it once folded in half would that not give you a straight line to sew on? As I said I am new to this so if it's a silly question, I will laugh with everyone eles, LOL!

  62. allison January 30, 2014 at 4:25 pm #

    You can definitely do that Cynthia…it will just take a lot more time! :)

  63. Cynthia Oxford-Fishman January 30, 2014 at 6:48 pm #

    Thank you for getting back to me so quickly!!! I will file your tip away and be sure to use it with my first quilt. I love your blog and all of your great projects. I am looking forward to learning from you and referencing your blog frequently!! I am so happy I found you today!!! Happy quilting!

  64. ellie May 25, 2014 at 3:08 pm #

  65. gRANDEBBIE May 18, 2015 at 11:26 pm #
