hello, got a question. is it okay to use different woods in the same box? well i got scrap pieces of 3/4" particle wood and scrap pieces of 3/4" 5 layer plywood. is it going to hurt the output that much? i got enough scrap pieces of both woods to make a whole box. right now money is tight to go out and buy a full sheet of mdf, i would love to. any opinions would be much appreciated. thank you.
