I just finished making mine, and don't know how I lived without it. I use a medium/small bedroom as my sewing studio, and between the bookcase, cutting table, sewing cabinet and large sewing table not much room left but the closet doors. tryed hanging large piece of felt in front of doors, everything fell off. Did a lot of reading and research, and discovered Insulation Foam at Home Depot. Measured my closet doors, 6' 8"...Picked up, by accident the 1-1/2" thick boards, glad I did. Asked very sweetly if they would cut it for me... said they aren't supposed to but would...had them cut it down from the 8 foot to the 6'8" then had them cut each 4 foot wide piece in half. Packed them all in my car and I was off. When I got home used cheap white flannel, cut to size, used 3M Super 77 spray glue. Folded flannel side to inside, used large pieces of duct tape to make a hindge on the back so it folds in half either when I put away or when I need to move it. can keep current project on the board when I fold it onto it self. Stands in front of closet doors at a slight angle. When I am working on a project the blocks 'stick' nicely to the flannel, when I start sewing strips, use pins instead. Whole thing cost me probably $20.00
