If you give up and want a vinyl one (as opposed to the ones on F+F), I do make them. *hehe* Just throwing that out there! XD But I tend to charge more than F+F, so probably not the desired route. >< heheh
If you decide to make one, I haven't seen the particular tutorial you're referring to, but I might be able to offer advice at some point in the process if you get stuck!
