In this album you see some of my Kakao Cards( or called ACEO).
This cards are in the format of 6,4 cm x 8,9 cm.
On official websites like kakao-karten.de or ACEO.com you can trade this your selfmade cards against beautiful cards from other Kakao Artist. Kakao Cards becam a very big hobby of mine, i love that small format, you just have such a lot options to let your creativity out.
Just try it and you will see, it will become an dependency^^
