i guess this is a old post but thought i would through my two cents in,
just concerning the tables, all the shops i have worked in have had the large woooden tables, with a plywood table top, but on top of that we place a sheet of HOMOSOATE, (not sure of the spelling )its a thick paper fiber like piece about the same size as a piece of sheet-rock, we lay that on top and then cover it iwth craft paper, creates a smooth flat surface on which to lay out patterns, pin fabric for cutting, and glueing, it is very versitle, and is easy to clean up, u simply un tape the craft paper and roll oyt a new sheet , both the Henson shop , and Lyon puppets use simialar ideas for thier tables, just a though for all you aspiering builders.
