return the vest and get your money back then go to a Tatoo shop and have a vest with the patches of your choice inked on. The days you don't want to show your vest just wear a shirt.
lol... That is the most brilliant post I've read to date regarding vests and patches on this site! I nominate you for moderator!
Ok, you've seen those little suction cup things that ya hang ornaments on mirrors and windows. Use a couple of those and hook your patch to that.
Another idea, link a chain or line to your patch and hang it backward around your neck. Do that with all your patches. That way, you can change patches as the urge moves ya..
I was kinda thinking maybe you could put in a few grommets and then run some nice chrome chain through, and then you would look really tough at the same time.
