I have a friend who is a long arm quilter and she took one of those Japanese folding screens and put quilts in each panel and uses it to hide her machine and frame. It also serves as a way to keep the wind that comes in her front door from coming into the room she works in. I don't know it that helps but she just made quilts that fit the panels and put sleeves top and bottom. Seems to work for her. I believe she used a lightweight batting. I would think maybe a lightweight cotton batting would be warmer or let less breeze through than a polyester which is more loosely woven.
