OK this is how to make HST easy:
You take the width of fabric and cut strips 1/2 inch bigger than your finished needed (HST) square size. You lay the strips right sides together. Sew 1/4 inch seam allowence on the top and the bottom. You now have a tube if you were to turn this inside out, but don't do this. Lay your easy angle or wonder ruler (Eleanor Burn's flying geese or fons & porter ruler also does the same thing.) You cut a triangle out, then open it up to make sure you have the right size. You can either sqaure it up or adjust your cut so that you have perfect sized HST. Notice in the picture for the next cut I flip the ruler and cut another triangle. We don't want to waste any fabric! It kinda looks like the 1,000 pyramid quilt....rofl
Herer is a hint!~! You can lay up to THREE!~! sewn strips down and cut 3 HST EACH time you make that ONE triangle!~!
