Technical questions

[soc_puppet]

A friend of mine is planning to make some crochet hooks. Since she's not a crocheter, she's looking for some technical info. I gave what input I could, but I figure more is better than less, so I offered to cross-post a link here. If you have a few minutes, please consider stopping by to give your own take on crochet hooks and how they work/how you use them. [Warning for discussion of use of mammoth ivory (and, in comments, other animal bones) as material, just in case that squicks anyone out.]

Thanks very much!
