To PM you go through a designer's profile page - for example, click on the 'RetroMetro_Steve' hotlink under my avatar above and you will get to my profile page and from there there is a 'Send Private Message' link. By-the-way, don't be afraid to ask for changes or experiments as you see fit. Cheers, Steve.
I've been reluctant to introduce too much detail, knowing the limitations of certain media such as silkscreen, embroidery (caps and such), etc., but I thought I'd put up this idea anyway. If chosen, I would include the simpler art for laser etching or whatever you might need it for.
