I have several machines and I have to keep all theaccessories straight. I use plastic pencil boxes to store the accessories for each machine. I labeleach box with machine manufacturer and model number. Theseboxes are the perfect size for my bobbin holders, Bobbin Storage Tunnels. I also labeled the cords for all my machines. I put a piece of velco oneach cord and write the name of the manufacturer and model number on each pieceof velco and leave that on the cord.
