naps fix everything, especially when a kitty joins you
I am in the same boat as you with the storage of supplies-- I have all of my supplies in a drawstring bag and my ponies displayed on my printer... not efficient at all, but I sometimes go to a friend's to work on ponies, so it's the most efficient :/
But when I get home over the summer (back from my dorm), I plan on using my extra plastic dresser that I use for clothes now for my pony supplies then. There will be one drawer for paint, one for ponies, one for hair, and one for sculpting/other
so many reasons that I can't wait til school is over...
as for the sculpting, I can only advise you on what air-drying sculpting material NOT to get: Sculpt-It by SargentArt. DON'T TORTURE YOURSELF BY WORKING WITH THIS STUFF...
