Swapping Patches On Shirts And Jackets

[Blue37]

I belong to multiple associations, and most of them require a distinctive patch. I have always bought shirts for each association so I would not have to worry about swapping the patches, but I am cutting back on my schedule and can no longer justify the expense of seperate shirts, so I am looking for a way to swap patches.

I found Aleen's Tack-It Over & Over in the Honig's catalog. Have any of you tried this product? Does it work as advertised? Does it harm the garment? Appearances are very important in my games. Does this hold the patch securely and look professional? One of my associations uses no patch. Will I be able to remove the patch entirely and not still see the remnant of the Tack-It? How about on jackets and plate coats?

They also advertised velcro strips. I have no doubt velcro will work in holding the patches in place, but how does it look?

Does anyone have another idea for swapping patches?
