There were no other rules except for it to be made of all current stock.
Earlier I purchased the Glamper Greetings stamp set as I love the look of vintage caravans.....to dream to own one just to deck it out all retro.... So for me it was a no brainer...my ATC had to have the caravan on it.
I must admit I sat down for several hours and made many versions of this until I got it just right. It was a lot of work to replicate this 30 times as there is quite a lot of fussy cutting. But that is what sitting in front of the television at night is good for. And how therapeutic is fussy cutting?
