I have some 2 liter coke crates. Is there anything I can do with then?

I’m into painting glass vases and globes at the moment. One of those crates would be great as a big turntable, painting rack, drying rack, spray sealer rack, storage rack, shipping rack to a show, and a display rack. Wish I had some. Best wishes ☺️

Keep them as they are, they may be worth something.

If they are not cardboard my first thought is use as a planter

Stack crates, paint them and make a storage area for a room. You can hang a mirror on the larger flat side and hooks on one of the other sides and a dry erase board or cork board on the third side. The open side can be used as storage. If you put the crates on a lazy susan the whole thing will turn.

Use the to store magazines, yarn, books, kids toys, shoes in a closet all kinds of things. I would not paint them, especially if they are wood and old.
