I thought this might help those of us that have wood molds:



The liner pieces are 3/16" lexan (1/8" would do, but the thicker material is more rigid and stays flat against the mold sides better). The pieces have been cut precisely to fit the closed box, in order to minimize leakage around the edges. My DH cut them with a fine-toothed blade on the table saw. When the soap is ready, the sides are opened and the whole block with liner pieces stuck to it can be lifted out. The lexan sides are then peeled off (you can really bend the stuff without breaking it). I leave the bottom piece of lexan stuck to the soap, and run it through my wooden cutter guide (also made by my DH). It slides through easily, and avoids picking up color from the varnished wood. The lexan is tough enough to withstand the cutter blade (a large scraper with handle).

Before pouring soap into the mold, the sides are closed up, then the lexan liner pieces are inserted as follows: First place one long side, then one end, then the other side and lastly the other end, so they wrap around the box as shown below, in the top view.Finally the bottom piece of lexan is pressed down firmly to hold the sides in place. The liner is sprayed with cooking oil before pouring the soap.

Just a comment -- cooking oil will saponify, so it really won't do much to keep the soap from sticking. Use a thin layer of petroleum jelly or mineral oil if you are looking for a mold release for your soap.
