I've used Primitive Originals a couple times. The sinew is really strong - you wont break it!. ( i think its 70lb test). i've been buying it in natural color. $7 for a 450ft roll. website is www.primitiveoriginals.com

: Looking for a good supplier for artificial sinew. Michael's Craft
: store had a spool, but it turns out that it is the fine stuff
: (#30) and I can't pull very hard before it breaks. Where do you
: all get your sinew from? Are there different weights?
