Playing cards

I have a fancy to tablet-weave silk braid onto the edges of some of my clothes. If I'm going to start tablet weaving, I figure I might like to try it on a loom. I've found an eBayer who makes tablet looms that look just like the ones in illuminations: a plain frame with a fulcrum and a tensioner. They take 30 quid for this, which seems reasonable. Any thoughts?

Also, I've seen cards in Boxwood or bone for about 3 quid, in other woods for one or two quid and possibly in leather for £1.50. Thoughts on cards, how many, how big or what materials?

I'd just email Lady Catherine Weaver, but it occurred to me that it might be cool to crowdsource the question to this list.
