I don't know how helpful these ideas will be but I will state them anyway-and PLEASE don't ask me to post pictures, my sewing room is much, MUCH too messy tonight.
I had with a previous machine no place to organize my numerous presser feet so bought a metal screw organizer--it is about 12" wide by 6' thick, by 8" tall (very approximate) with lots of little drawers and used a label-er to write on the outside of each tiny drawer which presser foot was in that drawer. Very helpful. I am also a machine embroiderer so bought a large cloth over-the-door shoe bag with 24 pockets for stabilizers. I used the label-er to put the type of stabilizer on each lid. I attached it to the back wall in the small walk-in closet rather than over the door.
We frequent auctions and my DH found built-in cabinets with a drop front, shelves on top and covered cabinets below and tore them out of the condo they were in a mounted them in my sewingroom. WONDERFUL! I display my 'toys' on the upper shelves and books and my laptop on one drop down. (My toys are my collection of old toy sewing machines and toys from my childhood misc.) Also found two matching tall narrow, shallow cabinets in the same white finish where have embroidery discs in them and lots of FQ. I do not remember what we paid exactly for each of these cabinets but the tall narrow ones were both for around $25. The build-ins around $100. The last item I also use I got at Home Depot is an organizer that you choose the wire baskets and whether you want the casters and a hard plastic top. Mine I put 4 baskets in, the top shallow and each one going down is bigger. This one was not cheap --I am thinking over $100 but it sits next to my machine and holds lots of stuff that I use frequently. I have collected all this stuff in the last 3 1/2 years so did not go out and get it all at once. It was a matter of watching auctions and going and looking and either buy or not buy. Oh yes, the white laminated cabinets that are made for closets (ClosetMaid is one brand) that are sold at K-Mart, Target etc. I got the 15 cubby hole piece made for shoes but use it to put the same color FQ for applique or stained glass quilts. It is pretty and handy. It sits on top of the tall narrow cabinets I mentioned earlier. Hope this gives some of you ideas . My room is small and I need it twice this size but I manage to do what I want to in it, clean it up and start all over again. LOL Sue
