Then if you don't want to layer a color between the cut down piece and the card base, you could follow this guide:
But since I needed some contrast color as another layer, I simply cut those pieces down after the initial cut. This way they ended up being 3 3/4 square and 3 by 3 3/4.
My pieces of DSP were 3 3/4 by 1/4 used with the square stamped piece and 3 3/4 by 2 used with the smaller piece. So you get a slightly different look...
All was layered, ribbon and greeting shape was added... and done with SIX cards, like that... very fast!
Oh and if you notice after you cut all the pieces down that you messed up on one, don't get mad... just make do:
