I have a lovely planned out sewing room. It was built by a local contractor right after we moved into this house. It is wonderful in every way except that with an ever-growing fabric stash, the three closets in the room are bulging, and I've moved into two other closets and a corner of another room for the stash. I need to clean out some of the stuff! I have several sewing stations, because I do costumes for plays, and often have helpers who need a place to sew. Besides, I don't want to get rid of any of my machines, so they each have their own place. If I had a place to put my treadmill somewhere outside the sewing room, that would make me happier, but I do need it in there to remind me to use it once in a while! Other than some lousy carpeting, it is just working very well. I do have a bedroom downstairs that is only used for guests, and it is big enough for me to put two craft tables together to lay out my quilts to make my sandwiches. This is what I use instead of a design wall. But I have a space for a design wall, just haven't taken the steps to create it, even though it wouldn't be hard to do.
