I am looking for something that I can use on my bench that I can stick pins in. For most larger wings I use a jig of some sort but I would like to be able to build right over the plans for some smaller designs. Years ago I could buy a product that I think was called Homosote. It came in 4'X8' sheets. It was like the 24"" x 48" ceiling tiles that you can buy now. I went to both Home Depot and Lowes today and found out that I would have to buy a case package of the ceiling tiles. Needless to say don't have a use for that many. Anyone out there using some other product that would fill the bill?
