Lot of hobby stores, hardware and home improvement stores have a hobby wood selection. Generally I would stay away from it. The main hobby wood sold is very light weight, very carve able and perfect for light planes, boats. Its balsa wood, which is so light, it would snap looking at it. I think most the folks are going to recommend a supplier of hardwood. 1/32 is really thin. That thickness, could probably be kicked up a little. I'm a constant book reader and have a variety of bookmarks. i know they are a bit thicker and haven't worried about breaking them. Just a thought, maybe your project requires that thickness. RJF
