I bought Lauan plywood a while ago to use as cheap material for constructing things in the workshop (e.g. work area in spray-paint booth). Using a cut off piece to test some of the settings on the laser soon changed my view of this material. The Lauan hardwood panels engrave very well – it is uniform and it allow for a very good scale of shades from light to dark. The wood itself is also nice when sanded and treated with some lacquer or oil. I thus started to use it to make engraved posters. The size of these are 30 cm x 40 cm (11.8 in x 15.7 in) but I am thinking of making large multi-panel maps.
Some of them are for sale here: BUY A WOODEN POSTER

I also made some book covers using this wood that can be seen here.
I am currently almost out of this wood but will probably get some more in the future.
