The Give Thanks... expression and acorn come from the For All Things stamp set. The middle card's expression is from the Feel Goods stamp set.
The top two cards are embellised with the Mossy Meadow ribbon and the bottom with a piece of Chevron ribbon.
Stamp, cut, layer, add ribbon! You're done! I love Designer Series Paper because it gives you a color scheme to work with and adds lots of pizzazz to your cards!
