I have no experience making it, so take these links with a grain of salt peter. Came across them while looking myself.
Mokume-Gane Metal Techniques with James Binnion J. Arthur Loose: Handmade Damascus Blades, Rings & Jewelry (Under Studio, Making Mokume)
Making Mokume (This is making Mokume from quarters, many sites, and posts in various forums cover this, it's a popular technique)
Ariel Salaverria Custom Knives - Damascus Custom Knives - Tutorials (An Argentine maker, who frequents many of the forums and posts alot of tutorials for his techniques, which tend to have a very 'Ariel' look to them. Probably does the most detailed photo tutorials out of anyone on knifemaking forums)
Hope that helps -MJ
