I feel your pain, as we basically did the same, about 3 years ago. I started keeping my craft supplies in lots of large Rubbermaid and Sterlite bins, stacked along several walls. Earlier this year, dh finished the inside of a large shed, so I now have a "sewing/craft shack." Invest in plastic bins. Lots and lots of plastic bins. Excellent incentive, to get that extra room done! ;-)
