I guess I just don't understand.
can't you just print a copy or two of the picture, size it to suit you self and use that as a pattern?
I realize that you may be cheating the designer out of some money but, If you tried to contact them and didn't get a response, that would be my next move.
I know that I will get some response to my idea and why that is wrong but, I am just being honest.
You are not suppose to make patterns of team or business logos because of legal issues but, if I'm cutting one copy of a logo for myself or as a gift for a friend, I will get an appropriate picture or decal that is published and use it as a pattern.
I feel that if I'm not trying to sell it or make money from making many copy's for sale, and it is just for my own use, who's to care?
