Everyone should shop at restaurant supply stores. You can get identical metal mixing bowls for a fraction of the price of the heavy bowls most people have. Plus they clean easily and stack, so you can have a dozen at the ready easily.
Need trays to alternately shelve while working on different hobbies or projects? Consider rolled-edge baking sheets and a baking rack. Restaurant supply has solved the problem of trays that do not warp and have no sharp edges or corners, at sheet-metal prices.
