I'd like to make a lightweight and portable felt-covered panel that can be placed on any table for gaming.In practice, I'm looking to make 2 identical panels about 5' by 1.5' (long and narrow to easily carry under-arm) that can be set next to each other for a 3'x5' gaming surface.Felt+foam will be glued to the rigid panel, wrapped around the edges, and stapled. Underside will be covered in a grippy rubber sheet. The three 'outside' edges of each panel will be lined with U-shaped edge trim.I'd like to keep these as lightweight as possible. I'm considering underlayment plywood from Home Depot, such as this.However, I'm worried about warping over time (or just getting a warped panel to start with).Questions for you experienced DIYers...Should I even be that worried about hardwood plywood warping?Are there any simple changes or additions to the design that will prevent warping/increase strength without significantly increasing weight (or cost)?Are there any other materials I should consider (that won't break the bank)?Thanks gang! via /r/DIY http://ift.tt/2AMIoy8
