All three cards use the paper quilting technique. It is what is done with the paper quilting after completion that is fun.
Embossing folders where used to add texture to all examples. The two green cards were lightly sponged with medium brown ink after wards to make the embossing stand out a little more.
On the pink card, the corners were rounded. The other two cards were cut out with Spellbinders Labels. They are all layered with coordinating card stock.
Stamp credits: on the pink card unknown, Stampendous and Our Daily Bread are the other two.
