Hi, Auntevie! there is a very easy way to do HST without having to deal with bias edges! Very easy also for doing a bunch using the same fabrics. You use 2 squares the same size, mark the diagonals and sew 1/4" each side of the marks. Cut between the "seams" and flip open. No bias edges! Here is the chart I've made:

And if you want many of the same you can make a grid for doing a bunch at the same time. Just google "HST grids"
