I bought some plywood from Michael's (1/4" x 12" x 24") that I am going to woodburn some designs on to. However, I'd like to put some sort of finish on the plywood so it looks more refined/elegant and not just like cheap plywood. Since I'm woodburning on to it I don't want the stain/finish/varnish to be too dark as I want the design to be clearly visible. I hear vinegar and coffee are some homemade options for finishes, which are appealing to me as they're cheap and easy but I have no experience with any type of finishing. So, any ideas what would be best for plywood and what would give me a light but finished look?
Any help would be much appreciated!
