Never tried that before. I like the idea. I have used burlap with great success. I would break the twine down to fine groups of fibers rather than leaving it all twisted. If you soften it and soak it in glue just like you were doing a sinew back bow it might even have the look. If you decide to give it a whirl make sure it is clean. Photo document the process and keep us up to date!
good luck!
