I don't buy rulers and some other things that I really don't need, but I have a couple of photo boxes filled with extra notions and rotary blades and I did have second rotary cutters until I gave them to DD. I'm always needing more notions and I prefer leather thimbles and they tend to stretch out after a big project, so I buy a few when notions are on sale and then I can get a fresh one for the next big project.
It's not silly or foolish or wasteful to have a lot of notions on hand. It's good planning.
Cathyre, I like your designing style. I wish Hubby would listen to me. I want to move our bedroom to what I'm using for a sewing room and move the sewing room to our bedroom. We only need enough room for our bed, nightstands and maybe a dresser in a bedroom, so we should move. I need a lot of room for a sewing room and our bedroom is so much bigger. He refuses. I don't get it. It's really silly.
