Wal, a thing of beauty!

You probably know this, but woodcuts are usually done on end-grain blocks, typically maple or boxwood, which can take a fine line. There are also quasi-synthetic versions such as Resingrave. I believe that you can also use MDF at least for test cuts to get the image right, and probably use something like PVA or dry-rot cure resin to stabilise the surface. Lawrence seems to be the preferred supplier.
