Ooh, they’ve got one that nearly matches my dog’s collar! Maybe I need to start using a strapI don't like leather, and I do like variety and handmade goods, so I'm going to recommend the QuiltsandUkuleles shop on Etsy. Nancy is a quilter who got bitten be the Ukulele bug a few years back.
Even if you're not a vegetarian, I think you'll be blown away by the variety and quality of these. Far superior to anything else I've tried (including the first ones I bought with leather before I discovered these).
