I have new rubber, but it's not as much of a spending spree as it appears... honest!
The two left hand sets are Graphicus Guild limited edition stamps. I know, they're not free, but they're great value and both useful sets.
The others are all Paper Artsy stamps that came as a gift when I renewed my Craft Stamper subscription, which had lapsed a while back. Lovely stamps, I like the swirly set. Trouble is, I've run out of EZMount so I can't easily use my lovely new stamps!
