I'll make it super easy on you... just send all that fabric to me! No muss, no fuss and you don't have to deal with all the organizing :)
It's easiest to focus on one small task at a time. Start with one tub, fold fabrics so they are all the same size and start laying them on the floor into the categories you think you'll use.
Then walk out and shut the door. Come back tomorrow and do another tub.
I can't wait to see it when it's done!
