Holsters/ how?

what kinda homemade holsters have been made 8) and i want to make one any tips?

I used a shoelace, a carabiner and one of those plastic string clamp things from the sleeve of an old jacket. I folded the string in half, and started the snake knot a little below the fold point(enough room to shove a yoyo). Continued the knot until i was almost out of shoelace, then tied it to the carabiner. After the final knot I slid the shoelaces into the snake knot so they wouldn’t stick out.
This one was too long imo. It liked to swing around too much. Personally I don’t mind having my throw in my pocket, so this has been out of service since the day I made it.
