This is a great idea and use of common items for a creative purpose. Not probably something I would use, but great to keep in mind. I don't play often enough and not in tourneys to worry about tracking tokens so much. Well done.
I got tired of tokens.
Doh! I forgot the crit tokens. Again. /facepalm
Much like the double-decker couch, this idea might seem good to the creator, but it is wrought with problems that have no easy answer.
Didn't the double decker couch end up saving them all?
I used the clothespin idea during a game I played this afternoon. I was flying a B-wing as part of my squad and the way that ship sits on the stand makes the clips hard to use.
I only used it for target locks and not the other actions tokens.
The biggest problem I see with these is accidental bumpage while clipping it onto the ship.
