I turned my dining room into my main sewing area. My hubby, bless his heart, took some old kitchen cabinets (donated by my friends who both had their kitchens remodeled) and made the sewing counters. He made a recessed area to drop my machine into and then the clear extension table slides right in (he's so clever).
Then I have a smaller room off the dining room that was my nail room (I did nails out of my house) and set up my cutting table and we just put the shelving unit in to hold my dwindling stash. (I used a lot of my stash in my sisters king sized quilt "Wish Upon A Star".
I am very lucky, I know, to have a very supportive husband.
