Thread: Fast way to do 8 at a time half square triangles (HST) with straight of grain edges!

Here is the formula I learned from Linda Ballard. Of course you put 2 squares together!

make 2 squares following this formula. Use the size of finished HST + 1" X 2 + 1/4". Put the 2 squares together. Draw fine lines corner to corner, another line down the center lengthwise and another across the center horizontally. Sew 1/4" on each side of the DIAGONAL lines. After stitching then cut on all drawn lines. Press, open, press and square up if necessary. I think adding the 1/4" gives some wiggle room.

i.e for 2" finished hst. 2" +1" X 2 + 1/4" = 6 1/4" squares

just googled this and found your tut. Thanks for posting it! very easy to understand.

WOW great tute...you have excellent math skills...and explain it very clearly Thanks

Thanks i need to try this.
Im planning on making a pink and white quilt for myself, and
Have an idea i just might need triangles.

I'm fairly new to quilting, this will certainly be a handy "tool" for me. Thanks for sharing.
