Vonna and all,
I really like the idea of spreading the word in a non-confrontational manner at events like the MS walk where people who either have MS or who love someone with MS will be gathering.
You guys have really taken it and ran with it and I hope this is carried into action!
I'm somewhat of a graphic artist myself and definitely in the marketing arena, and I really like what you're doing with the logo and short and hat designs. Grabs attention quickly, and opens the way for questions.
While I love the MS tie in for Multiple Stenosis, the only issue is that nothing remotely close to CCSVI comes up when that is Googled or Binged. I'm definitely NOT shooting down the idea - I think it's brilliant! But I know what you're talking about.
Just a thought because so many people might not ask but will write it down and Google it for more information. (I do that, I'm pretty shy in person!) If you can get that tied into your site and into the search engines for that by the time this goes into action then you have zero issues.
OR include a website address on the shirt somewhere.
A thought for the sale of shirts/hats/whatever...cafepress.com (it is US based, so is there something like them that is Canadian?). It's free to join (basic store), free to upload your design and choose what merchandise you want it on - shirts, hats, mugs, waters bottles, even stickers, magnets and pins. Unfortunately there are no business cards.
Something like that would take the pressure off of you to have shirts, etc. printed and then hope to recoup your initial investment. Especially if you want more than one item (shirts & hats) printed, or more than one design offered.
Just offering up a couple ideas to help the cause!
