I have to be honest with you about my colorful papers, even if this is so easy to copy. I use antique stamps, mostly from the years of the 1950's 1960's. 

How i get them?

I met two stamp collectors, who give me usually 2000-3000 stamps to sort out which is the perfect color and topic for me. It takes me approximately 2-3 days to choose which to buy, and another week (at least) to decide what to make of each. And still i have surprises if the quality of the print is so bad, that the liquid i use just makes all the colors turn into one, big brown mess :(

But when i find perfect ones, i try to search for them again and again. My favorites are from Nippon and Switzerland. 

And it still happens, that i have to wait more than a year to buy another piece of the same stamp.
