That piece and 4 or 5 more will get you there.  ;)  I usually go 2 to 3 layers, depending on how thick I apply each layer.

I would sure go with tendon sinews to back the bow, backstrap sinew is good for bow strings and sewing.

I'm no expert either and have only backed 1 bow with sinew. I used back sinew and haven't had a problem but that could be because it was used more as a backing to hold down some splinters and not used on a highly stressed bow. I would think if it were applied properly that back sinew should work in most instances. Am I wrong?

No Fred you are right it will work just fine but tendon sinew breaks down much better and contains many more fibers per piece and I think it lays on the bow better than backstrap sinew. All my early sinew backed bows were backstrap sinew because it was easier to prepare, once I tried elk tendon I have never looked back. It is much more labor intensive but worth the effort.
