Mmmmmmm. ok soundsa interesting. Where abouts do you live..?
Here on the West Coast there are quite a few other species that are good for bow making.
This is something I found out about Spruce. Beside using YEW for bows and other woods they also used spruce to great extent.
Spruce is valued for its wood, which is light, soft, and relatively strong and flexible.
Aboriginal people made spruce saplings into snowshoe frames and sometimes into bows. They heated the gum to make a glue to fasten skins onto bows and arrowheads onto shafts.
