I made a quilt using the quickie method using layer cakes. I starched all the squares first and had no problem with them. I also made 2 quilts for kids using the same method. I guess if you count the time you spend starching, you're not really saving any time, but if I am sewing biases I always starch anyway. If you sew accurate 1/4" seams and don't pull on the pieces there shouldn't be a lot of squaring up. But then again don't you have to square up most squares anyway, whether they are HSTs or not??!?!?
