I have them done and everytime I play with this fabric I love it more and more. I also love doing HST.
I can never see why people have trouble with them. They can be time consuming if you are making a lot of them, but if you break it up into small batches it isnt so bad. You can see how much I love doing HST is the quilt picutred below. This was for a coworker having her first baby. She had told me the colors for the bay would be yellow and grey. After scouring the internet I managed to find just what I wanted. You cant see it in this picture but it was the first time I FMQ circles on my domestic machine. The "quilt police" wouldnt be happy, but I dont care....lol
