I agree with rotary blades, scissors (why is a pair of scissors $20.00 or more!) and I lose those pesky seam rippers all the time (maybe that is a sign I don't need them!). Also, I can't justify the costs of patterns. I haven't bought one yet because I was given one at Christmas and to be honest I don't know if I am just an idiot or what but I have no idea how to read the directions! No problems with the free patterns I have downloaded though! I'll stick with free!
