You just use the piece as a template. Score around the piece with a scalpel/box cutter. You then very gently and carefully (not to cut your self) scrape away the wood inside the template, a little deeper than the piece. Cover the inset with a gene rouse amount of PVA. Lay the piece into its place and cover with grease proof paper. Use a heavy book or weight over the paper and leave till set. You will then need to gently peel off the Fablon backing and sand away any residue PVA glue. Make sure the glue has totally hardened before sandin. VOILA. DEB X
