I share a sewing space with a spare bedroom in our home...well, minus the bed! (It's still a work in progress) Until recently I had my fabric, patterns, etc. stored in big plastic bins against the wall, struggling to find things.
A couple of weeks ago I purchased 2 bookshelves/cabinets on craigslist for $160 for both. I was able to completely empty 4 of them and still had space for my yarn, a spare sewing machine and several WIPs.
A daybed is in my future for that room...
