I have made so far, 5 yoyo/kendama holsters. They are made out of green rope with yellow stripes. This is what they look like:
They open and close to hold the yoyo in place. I was able to find a thin, cheap and strong rope to make these with. I have made 5 of them, because I ran out of rope, so I need someone to buy them. Once they are all sold, I can buy more rope, and some carabiners. These will ship without carabiners, because I only have 1. am selling these on my BST for $5. $3 for shipping, $5 for shipping with tracking.
