Awww.... Though I'm curious about what resin you're using and how it works. smile Resin-casting is on my list of things to learn someday.
I'm going to need a larger suitcase for my studio stuff, I've realized... I think my calling my favorite store just now to order markers when both my cases (that barely fit what I'm using now) are completely full. Meaning I'll have to pick up a new case too.
I've been using a carry-on sized piece of rolling luggage, which will hold generally markers, cash box, and most of the merchandise (plus portfolios and at least some signage). I generally carry bristol and a drawing board in one padded freezer bag, and my display wireframe, tablecloth, etc in another. And then the toolbox in my hand. And a backpack with laptop and other miscellaneous stuff wedged in on my back. I CAN do it myself, but it's a bit awkward. So... bigger suitcase that still rolls and holds all the stuff divided between about four bags? Do want.
What sort of systems do people here like to use for transporting their table stuff?
