Hey folks. 1 Granddaughter is highly allergic to seeds and nuts. I’m turning a couple of walnut bowls for the wife and I to use but on the off chance that the grand grabs one, what would you folks suggest as a safe finish? We do know that she can handle my turnings of various woods so it’s more about the finish. Walnut oil would be a concern. Or go to a stand by such as mineral oil? Thanks!
