Here are two cards from my VERY talented card club buddies: The top one is from Mel Morgathaler and the lower one is from Janet Shannon. I love Mel's use of clear VersaMark ink to stamp a background on the gold (More Mustard) and green (Mellow Moss) cardstock. She also used a background stamp from Stampin' Up called "Linen" to put a subtle texture on the gold cardstock. These details enhance the overall style of this card, and the saying she used on this card is one of my favorites!
Janet's adorable little monkey card included a lined coordinated envelope - such a nice surprise when I opened the card! You can simply trace an opened envelope on the paper of your choice, then cut it out by cutting in approximately 1/2" along the top flap area (so the envelope glue is exposed), then adhere this piece inside your envelope with your favorite adhesive. Try this wonderful technique on your next card!
