I use empty "Tic Tac" containers for used needles and bent pins. I use a prescription bottle for used 45 cm blades. I use snippets of oxygen tubing and wall anchors to put over the sharp points of small scissors I have lost the covers for. I have a plastic box for fishing to hold all the feet for my machine. I used a sharpie to write on the bottom of each section which foot goes in that section. It has room to hold thread, needles, scissors, etc., so when I go to a retreat or class, I just grab the box and it has everything in it.
