Our Wood Rocks DIY Form allows you to skip the hard part and go straight to the fun part! This reusable form eliminates a lot of waste, the project comes out smooth which makes for easier finishing for the DIY'er that doesn't have all the big wood tools. These forms are 12" by 20" by 3". It is a 2x4 wood frame with MDF base. We use threaded inserts with bolts to assemble. They are lined with HDPE which does not stick to the epoxy. Each form will come with a set of instructions and a digital video showing each step.
