I actually very much appreciate the thoroughness of the advice, especially as someone with a vintage pennant that I've been trying to figure out how to display. It is sufficiently rare and cost me enough that I want to do it right.
But I have to also agree with the others. The process you described will cost hundreds of dollars at a frame shop. Perfect for some items. But if I just picked up a pennant at the team shop for $5, I'm grabbing three push pins and tacking it to the wall.
Assuming everything might have future collectible value is how you end up with boxes of unopened first year Stadium Club Hockey cards taking up space in your closet. Not that anyone I know has those.
