Oh I know what you are goin thru...Had sewing room but Mom moved in so that took care of that! Fab storage is the worst. Have 16 or 18 66 quart containers stacked in our bedroom. They USED to be sorted by color. Sewing table in corner of dining room. Luckily its large so I can store my rulers and notions on top.
Can you claim a closet? Get rid of clothes that you haven't worn for a year? Get rid of DH clothes he hasn't worn in a year?
I used to look at pics of quilters sewing rooms and don't anymore. But when I was looking, I liked the idea of taking beautiful curio cabinets and storing fab! DSs are young adults so we are more flexible w/meals and one son works nights.
Good luck w/this. Remember, quilting is therapy. You will get this under control...eventually.
My family got used to the fact that my sewing machine is up all the time and our dining room table is usually my design/cutting table.
