The inside reads "Time to Celebrate". I picked this stamp up in a bargain bin during my recent visit to Australia.
Instead of the usual mechanism of round sticky pads, I made a column of washers and a small round magnet the same size, which was strong enough to stick to the 2 pennies as well.
Time has not exactly been on my side recently, though I have been busy in my craft room this last week. Hopefully I'll get around to publishing some other work in the next few days.
