A sourcing idea just came to mind in reading this. I don't know whether you live in a populated area or not, but you might consider checking craigslist and such for yarn. In categories of goods that people tend to get "overstocked" on, craft supplies is WAY up there. People take on hobbies all the time, get all kinds of supplies, then interest fades, or a new hobby comes along (and we BPers are of course are completely unfamiliar with this phenomenon! <cough> <cough cough hack! cough cough>) Where was I?

Oh! I know that yarn can be kind of pricey, because my sister knits (you know, complicated patterns and everything -- and scarcely needs to even look at it while she's doing it(!!!) I cannot fathom this.), so I've been to some shops. It's hard not to be drawn to the super-yummy ones (I think they might have some kind of magnetic gizmo tucked in there ). Heck, I get drawn to them and can't knit at all(!) (Reference: xmas 2005, in which an intended gift hat remained in the form of a paper bag full of expensive yarn. Considerably more than a hats-worth. And yes, someone did get it. For free!). Especially as you are starting out, working with such a bargain helps keeps fun high and perceived pressure low.

In an area I do know....metalsmiths begin by gaining their chops working in copper and brass. There's a reason they don't start out on silver and gold. Among other things, the "stakes" create an immobilizing intimidation that is not conducive to fun or learning or the creative process. In total contrast -- working with something gleaned from the metals recycling place -- one can experiment with abandon. And THAT'S FUN!

(Not saying you would be silly like me. Set out to relay the sourcing, value and fun of a bargain. Then got carried away... Ooops.)
