If you don't work with wood, you have a lot of options like insulation foam, spray foam, cardboard, foamboard, and other various materials. Making it from either foam board or cardboard would be easier. Just cut out two replicas of the fork and you can reinforce it with wooden dowels or sandwich more cut outs together. Then once done, coat it. Whether it be gesso, plasti dip, mod.podge, or I like to.use poster board. Seems more cleaner to me. But! goodluck!
