These are easy-to-make drop spindles. All you need is a weighted round piece, like a lid from a jar, a bbq skewer, wooden dowel, chop stick, pencil or even a paint brush, some sort of hook and duct tape or glue to hold it all together
This spindle was made from random things in my best friend's tool box; a paint brush, vintage wall hook and some duct tape to secure all the parts.
I tested most of these and they really work. The nescafe spindles were the best in the end, though.
