This piece of mahogany detail from a victorian sideboard had carved losses. First a clean glue edge on the broken piece was prepared. Next a new piece of mahogany was glued on to the original in the shape of the missing area. Once the glue has set. the surface is carved to match the original, and stained to match. It was then sealed with shellac before refastening it to the door, and waxing. A good on line source for (hard to find) hardwood is http://www.gilmerwood.com/.
