The yarnbarns are nice, but I made mine out of an old plastic coffee container. I just washed it out and then the top I put a large gromet on the lid. Popped the yarn inside and passed the yarn through the hole and there ya go a yarnbarn. Of course I decided I didn't like it because I couldn't take the yarn out once ya start the project. I still have them just in case I want to use it again.
I am very frugal at times so if ya don't want to spend the money on the yarnbarn try the gromet and any can you like.
