I don't have any little panda stamps - but I do have a big Sizzix Panda die that I purchased quite some time ago (on sale) and haven't used yet (this seems to be what I say every time I post lately?! I might be shopping too much?!)
This fits inside a regular A2 envelope when it's closed, so can be mailed easily.
I added the enamel dots to mimic the ones her panda is juggling!
I have a photo of the panda card closed in my gallery next to this one here.
