I love those. I bid on one of those little square one's years ago at our local quilt auction where folks brought their orphan blocks, members picked one, made something out of it, it got brought a few months later and was auctioned off to the same guild members. anyway, the proceeds go to filling our holiday stockings (also a guild project) to give to a shelter for the holidays. anyway, I keep my little square box just behind and to the right of my machine and it holds everything. Tweezers, seam ripper, spare needles in a box, a small snipper, safety pins, even a small ruler, etc. I could not be without it now.
