Q&A for How to Reuse Old Clothes

Denim you wear on the bottom half of your body is different than chambray, which is a denim-like material most "jean" shirts are made of. The denim of your jeans is likely too stiff to be worn as a shirt, and there would likely not be enough fabric for the body of the shirt. You could sew a pocket made from the denim of your jeans on a shirt though.

Have a garage sale. If your clothes are in good shape, some second-hand stores may buy them from you.

Yes, of course.

You can use it as a bedspread, or cut it into shapes and make new clothes.

Make a patchwork doll. Usually hand sewn, take scraps of fabric from your clothes, and sew a doll. You could make a patchwork stuffed animal, or anything sew-able (but not necessarily toys) such as quilts and pillow shams.

You can restyle it by making little slits at the bottom of the shirt and tying them together. You could also cut out part of a the sleeves or cut out part of the neck.

You could use them for rags around the house.

You could try to make a teddy beat with it. Try to line up the stains at the front of the bear, then draw with a marker a little heart or other shapes on top of the stain. Or you can cut out strips from the shirt and weave them to make bracelets. Or you can just use them as rags.
