Love your "little sewing room".
My sewing cabinet sets behind the couch in the living room, and folds down to look like a regular piece of furniture, just in case there is ever a situation or holiday that might warrant putting my sewing machine up. I have fabric in tubs in the garage, and batting stuffed in the bottom of the coat closet. I just have to put my mat on the kitchen table to cut out, and set up my ironing borad in the kitchen.
It is a wonderful dream that I might some day have a roon of my own to quilt and sew in.
Whatever.......... I live here, and I am having FUN......house inspectors are not invited in.
