I started my background by stamping the plaid stamp in one corner of my card using turquoise dye ink.

the only tricky part of doing this background is deciding how often to stamp the first ink color and making sure you leave enough room for the second. But I always do the 4 corners in the first ink color.

with a "normal" average size card I also stamp the center of the long side. ultimately I'm shooting for the white triangles you can see along the edge.

I stamp my second ink color (ultramarine dye ink) covering the triangles. don't worry about the messy center of this card, I'm going to cover it with my next layer.
