Agreed, at that size I'd say on the side, and order one. The center one would look better if it were bigger. or maybe a round velcro back that's the same size as our typical round patch. I could go for that and interchange our patches to suit.
Too many of my older decals were giving up the ghost, so I had to remove them. I’d still like to commemorate those events, however, and thought patches would be the way to go, as recent ones already have them.
