First, I have to ask- are you having trouble replying to blogs you are subscribed to? Blogs that I have followed and commented on for years are not allowing me to click in the comment box. I have done an online search on this topic, but found nothing. Whether it is my phone, laptop or desktop, can't comment.
Every once in a while, I find a layer cake that snags me because of great price for comfort quilts. This one was from Etsy. My mother can sew some straight seams and I prepped the stack of batiks with a white brush stroked layer cake on Daily Deal from Missouri Star. I spot glue the corners with washable Elmer's glue that I set with an iron and give my mother the stack. She hates pins. I tell her to sew off each side at the corners and then pivot down the next side with seams on all four sides. She sometimes does. She sort of pushes the fabric through like a speed demon to finish. When I get the stack back, I cut them on the diagonal twice and then use the Perfect Slotted Trimmer tool to make them all the same size. Then I open and press the HSTs. Only 2 trims instead of 4 sides, still time consuming, but worth it. Yes, the edges are all on the bias and I iron with Best Press to stabilize.
Since I use this method for a lot of comfort quilts, I am always trying to come up with new ideas. I found my graph paper and sketched out a good sized quilt. I had to add a column on either side so the quilt will finish 60 x 72 (6" finished HSTs). It took 96 of the 160 HSTs, so I have some extra to contend with and use later.
