Solar filter

I've got a piece of Baader AstroSolar film, and I want to make a filter for my refractor. I figure I can mount the film between two sheets of cardboard, but what's the best way to attach the filter to the dew shield? I'm worried that tape would fall off. I recall someone using an embroidery hoop, but I have a small scope, and I'm also afraid to put the film under too much tension. Suggestions?

Jeff,
Check out my design that I did for my 10" SCT, you may be able to do the same thing for your refractor...
