This is more of a woodworking question, I thought sign makers could help. I am making a large sign for someone who wants it made of plywood but have cherry letters inlayed partially into the plywood so they are raised a 1/4" above the face of the plywood. I've done inlay before but not with the combination of hardwood into plywood. My question is will this work with seasonal wood movement from the hardwood letters inlayed into the plywood? This sign will be placed outdoors but in a sheltered area.
