I do have some small and medium boxes saved and I do save gift bags if they are in good condition. The boxes i use to send gifts to my sisters who live in another state. It is ok to save this things, but within limits. But please, do not store your fabric in cardboard boxes, actually anything. Use bins. If, Heaven forbid, there is a fire, cardboard and paper, it all goes. A plastic bin will smolder and you have a better chance of saving what you have stored. I don't have anything stored in the house. It is in the storage shed.
