Scalple for seam ripper.
Recycle boxes from Vitalicious (diet treats I order on line) to put fabric projects together. They come in a nice box
Cheap table cloths to roll up my projects when I have to stop. I sew 2 or more together for big projects and store under the bed.
A printer's type holder for thread. It's on the wall, wooden and looks cool
Along with plastic note book sleeves, I use the smaller photo divided ones for the little freebies from the mail or that I pick up at shop hops, etc. 4 slots to a sheet.
