If you have any real matchbooks, take a look at it--then you'll know exactly how to make one and can do so in any size you wish, just using it as a guide!
You can also do an "advanced search" here at SCS--just look up in the dark blue bar, and under "Welcome, ___" there's a "SEARCH" button.
Go for advanced search, input what you are searching for, i.e. "matchbook", and select where you wish to search, if you suspect it'll turn up in a particular forum, like "techniques", etc.
You can find virtually anything that way here at SCS, if it is indeed here.
Otherwise, try a "google", and I'm sure all kinds of links will turn up with detailed instructions, etc.
