First off…things always look better in my head than they do typed up, so please try one block and see how it works for you before cutting up all your fabric. Also, if your a perfectionist this method might not be for you, some of your points and seams won’t perfectly match up…but it will take you about 1/4 of the time of other methods. Enjoy and let me know if this works for you!
Cut a piece of heavy weight card stock into a square 8″ big.
To figure out how to make different block sizes: Figure out the finished block size you want, say…5″ so you add an inch to that and cut your template 6″ square. Now you’ll have to figure out how big to make your strips. So divide 6 in half ( the size of your template) …so you want your finished double strip after its sewn to be 3″. Now the tricky part is figuring out how big to make your strips including the seam, my seams are usually .5″ ( 1/4″ + 1/4″) so add that to 3″ (how big your finished strip should be) Which leaves you with 3.5″ which you divide in half and that’s how big to make your strips….. 1.75″ wide. That sounds right in my head but beats me if it will really work! Try one first just in case!
If you want to make this with a Jelly Roll, you would cut your template 9″ square and it would leave you with a 8″ block. But again….I haven’t actually tried it so make sure you try it before cutting up all your fabric!
