Running roan tack makes really nice ones! I'm like you I'm drawing a blank on others but do a Facebook search there's all kinds. Designer custom ropes makes some nice purses! I found them the other day.
Look on FB for Hills Edge Leather. Whitney does amazing, quality work! I've had her do a few custom pieces for me and I've never been disappointed. She's a bit pricey, but that stuff will be an heirloom!
