If you use batting as a design wall, you already know how stray threads, hair and lint love to stick to it. Try using small bits of left over batting as dust rags or cut them to fit a sweeper head.
If you have a small space or your sewing room is in an attic with low walls, make design panels from sheets of foam insulation or other lightweight but sturdy material that won’t buckle when leaned against something. Cut down to a convenient width and cover with a flannel sheet or a flannel backed table cloth. Make several and bring out only as many as you need for your current project.
