Again rulers - especially the "rolling rulers". I suppose If I were to draw again they'd be useful - but not for fabric.
Binding clips. I went back to using two long straight pins and much prefer it. Yes - they get bent, but that is why I just bought a new box of straight pins.
Thimbles. I've tried about 5 different thimbles now and hate all of them. Have come to the conclusion that I hate thimbles and will just develop a callous on my middle finger and grow my own thimble.
Some of the BEST purchases I made: the super size Beba cutting mat (the clear kind, not the self healing), the "Spiral Eye" needles, and I usually pick up batting at the shows because it's so cheap.
