CaneTop.foocad

Place on the top of a cane to prevent eye damage if someone trips and fall onto it. This is often done with corks, cans and other upcycled items.

I wanted something that looks nicer, and also supplies a perch for birds (instead of on my chairs!!)

For fun, I've included a mini tray, which can be placed on top of roundPerch to add a few seeds/peanuts.
