I really like this pattern that has 16 and 4 square blocks. I used oriental fabrics for these blocks.
Fun way to use striped fabric:Couple of scrappy quilts using up leftover 5" squares
I got several backgrounds using this method and let the paints dry thoroughly.
Later, I used a raw piece of corn on the cob and ran it over a black India Ink pad, then rolled it onto the left side of the ATC. I then used this same ink pad to color the edges of the ATC.
