nope they dont look mundane, seems you need to maybe market them better, ie check the boxes on pinpics listing for who wants that pin, see if any of them are folks you have traded with, check thier trades, and see if they have something for you!! Then you initiate the trades, send out the request. Yes it is a bit more work , it might also help if you were willing to offer "better" deals, if you would rather trade more for what you want or what you can trade for what you want, be willing to get rid of what you have that you know you cant trade.
Ie -- three rack pins that no one really wants are worth just that, not much, BUT , if you can offer someone three medium pins for one of thiers most folks will consider it, you may not get acceptance on all, but more people will stop and think about it, you wind up with at least one pin you want or feel can trade better than the ones you have!!
It also allows you to be generous in trading building better karma for future trades!!!
just a thought or two , but then again, iM blonde,male and old, what do I know!!
Happy Hunting!!
