I gave up trying to find a suitable art box to lug my art stuff around in.
I have too much stuff to fit into my purse and too little to necessitate an entire tackle box so after cleaning out the otherwise unused downstairs room and transforming it into a work space, I found a couple of old pencil cases given to me a while back and altered one to make a usable case for lugging my art stuff around.
.....then I made pom-poms....
