Oh, your room reminds of my "little attic" in our "old house"...I loved it so. On that sloped ceiling, where the side wall is so short-on one side, I made my DH put in shelves the whole length of the room and that was where I put my stash....then had him hang a long length of gas pipe, put hooks on it and it held my templates, rulers, etc., like hangers on a closet rod.....It was my place, I wonder what it is now???????? No I don't want to think about it......
I have a sewing space now.....part of a finished basement with windows so I am happy here too........but my "little attic" will always hold a special place....
