The pastels shown in this homemade trug are the medium (read: oversize) Unisons, and some big "homemades." It is crudely made, but still working fine after several years!
Homemade trug: utility knife, Elmer's glue and Foam Board are all you need. Mine does duty as a carrier for odd-size pastels. Hmmn. I think I'll make a couple more for my charcoal and drawing tools.
