Symbolism help

[wolfshark]

I'm working on a prayer shawl for my mom. I'm crocheting it in Paton's Silk and Bamboo combined with Lime and Violet's Intention yarn, which is wool.

I'd like to write a letter to mom to go with the shawl when it's finished, explaining the symbolism. Here's the problem - I can find a lot on the symbolism of bamboo, but not much for silk or wool. Apparently my google-fu is weak.

Can all you fabulous crafters help me out?

Yeah, I intend to write my mom a letter about the shawl when I give it to her, both with the symbolism of what I used and why I chose what I chose. I figure that might get some happy tears :)
