I shop at all most all the places listed...but do find some great buys at my local quilt store.....in the back room....:-)
Patrice, I have some of those wobbilleeeee...stacks...my Dh put a solid wood base on the bottom and then the rollers on and then he screwed the stack together to keep them from falling apart when you tried to move the stack......I don't recommend carpet floors.....makes it harder for them to roll....I love mine and they do help keep things somewhat organized....I put different size blocks and and strips in mine....:-)
