I've found that you can add different types of wood to the software work space. Locate a sample of wood from the WEB or take a digital photograph of what you have in stock. With a graphics program, I use PhotoShop, convert the graphic to 512 by 512 pixels at 72 dpi then save it with the name of the wood, (Maple_Natural) as an example. This can be placed into the carvewright/wood1 folder and will now show up under the board properties. If you have one that you have stained use the plus sign to indicate a stain option (Oak_Light+Walnut or Oak_Dark+Walnut) depending on how light or dark you stained it. So far I've added a few like cedar, maple, and cottonwood but I don't know the size limits of the folder.
Have Fun.
