While I have grandiose plans, I have only been effective at making changes in my own realm of the production.  This last show, Gemini, I bought 85% of the show's costumes at thrift stores and 5% pulled from stock.  My favorite thrift store refashion was a leopard print shift, that I turned into a fabulous night gown. Of the few items I bought new, a couple of them were made of organic cotton. The rest were regular cotton.  The new mustache was human hair, (but alas the extensions were synthetic.) I bought cotton wash clothes instead of babywipes for removing makeup--which was a big hit.  I left a small basket in the makeup room to leave the dirty ones.  for some food props I used flour and salt dough instead of sculpy as well as just dried out food. The "wine" was organic cherry juice from glass bottles.
