Cork trivet frame

This is the second one of these that I have made as a gift. I believe they are intended as a place to set a hot pot, but also look good as a display piece.The frame is made of 1×2 poplar. The inside dimension is 5 1/4” square. There is a rabbet on the inside edges of the frame on the back to receive the hardboard backing. The finish is Zar oil based wood stain (#124 Rosewood) and a couple coats of tung oil. The corks are hot glued into place.
