I saw something the other day, a new way to do HST. Take 2 squares of fabric, place right sides together and sew 1/4 in.seam around all four sides of squares. Then cut on diagional twice. basically cut an X in the square. Open up the pieces and you have 4 perfect HST. I tried it and it works great, now I just need to figure out what size squares you need for different size HST. Can anyone out there help? I am so not a math person.
