Awesome! I work at a quilt shop... and the folks that run it started out recommending to us the Magic Spray Sizing... then, mysteriously... their work started coming into the shop... suspiciously STIFF and BOARD-LIKE!!! LOL... Yup. They have all (like you and I) have gone to super starch. I think they spray... but I mix my own!
and... I love it. No frayed edges to my blocks... all crisp and nice. I just like finding more ways to starch QUICKER. Thanks for all the tips! Yours were great!
