My card is made of layers of fabric, lace and paper but is still light enough and flat enough to go through the post.
I stamped a couple of grasses from an Artistic Stamper set on to a square of muslin.
My fabric and paper was layered before hand sewing - a little crooked I see now although it doesn't look so bad IRL! I decided that it would look nice layered on top of a fancy die cut but when I checked it didn't show much...
..no matter, I just cut the die cut in half as I knew the dips wouldn't show when stuck down
I cut out two colours of the Happy Birthday sentiment and slightly offset the top layers that it showed up more.
Thanks for looking, Chris
