What other strap might work though? A chain strap could be nice but it doesn't sound like the most comfortable thing to have digging into my shoulder. Hmm. I was going to just look for two giant o-rings to attach somehow, but I'm having a surprisingly hard time finding them! I even checked Mood's website and all they have are wood rings. I'm not too familiar with the garment district (well, at least not in terms of actually shopping for textiles and notions and such).
I did discover that I could possibly have the peg moved and placed in a different location to add length, so I think that might be easier.
