I live alone and my tiny 1 bedroom apt is my studio ! Actually, I sew on the table in the living room and am lucky enough to have a separate "sun room" that I cut, iron and store things in, but it has a door where I can close it off when it isn't in use. Since it isn't "conditioned" and this time of year I usually keep the door closed unless I'm working in there. For whatever reason, and I just don't know why, my sewing hasn't spilled over to my bedroom. I did use my queen size bed to lay out a quilt top with backing and batting and baste it. (Actually, there is a sewing machine stored in the bedroom between a love seat and the wall.. ....) My "cutting table" is an old table top that I have a mat on; it is small and I'm forever having to move stuff around so I can use the entire top for cutting. My "dining" table is a small round top and it has at least one sewing machine on it and isn't conducive to cutting.
I'm not hosting any Christmas get togethers so it doesn't matter. I did have folks over for Thanksgiving and it did take me a while to get sewing machines and other sewing stuff put away.....but the funny thing was my guests wanted to see my sewing machine and works in progress !!!
Years back when I was married and we had a big 2 story 4 bedroom house, I had a sewing room upstairs and it was easy to just leave it.....but oh, would I rather have that house back AND the marriage, OR, my little 1 bedroom and peace !!! Thoughts to ponder !
