so for a bit of contxt, ive been designing a desk for myself but when it came time to buy the materials i couldnt find a full size plyboard that was either within my price range and that fitted my size, what i did find was a couple of recycled 200x50mm boards that are in my price range, but the thickness is a bit mych and it would be more efficient to divide them and make more planks, but i dont know if there is a thickness that it need to be to be able to cut it or if its too thin.
