Adjust the Size of the HSTs by Changing the Width of the Strips!

Most methods for making half-square triangles start with square pieces of fabric. You can make two, four and even eight identical HSTs at a time starting with two same-sized squares.





But, have you ever wanted to make half-square triangles from 2 1/2″ jelly roll strips? There’s a simple process that makes that doable, and that quickly produces several identical HSTs in the process. Nice!

Lindsay Conner has written a tutorial that clearly explains the process. Notice how she used tape on her ruler to facilitate cutting the triangles.

Lindsay’s method produces HSTs that measure 2½” unfinished (2″ finished). However, there is some waste involved. Read the comment by Paul at the bottom of her article that explains how to get larger triangles with no waste.

Katarina used a similar process but placed the ruler differently for nearly no waste. She started with 2″ wide strips to create 2″ finished HSTs.

But what if you want HSTs of a different size? One way is to adjust the size of the triangles cut from the strips. A second is to adjust the width of the starting strips. Play with scraps to determine the appropriate strip width and ruler placement for the size of HSTs you want.

HSTs made starting from strips have bias edges. Starch the fabric before starting to ensure that the HSTs sew neatly together without stretching.
