There are many reasons I love being married to an engineer. I'll show him what I'm working on and he'll head down to his shop for a short while and come back with something he made that makes my job so much easier - like this super handy pom pom tool.
Basically, a little paddle I can hold in my hand to wrap the yarn around, instead of using my fingers or a piece of cardboard. He even drilled a tiny circle at the end to hold the tie off string. Brilliant!
