Build
Make small sculptures out of random bits of things you’ve found or have left over from something. Attach them together using glue, wire, string, or whatever else you have.
You could also use these same sorts of objects to decorate an old box, a jar, planters, etc., and include pieces of cloth, old coins/tokens, papers, and other items.
Before you do this, use these items as stamps to do a little creative printmaking or mark-making. You could do the same with anything that’s left over.
