Here is my card. I used the PTI Vintage Picnic set as the basket in the Pottery Barn catalog reminded me of this set. I did not have the exact colors mentioned in the copic color challenge and I used the nearest ones for the brown and orange. I did use the Spanish Olive color,
I used the PTI Polka Dot Basics II set and stamped directly on the Kraft CS. Then I adhered the PTI Bitty Boxes DP (This is my fav DP). A bow with button completed the card.
NOTE - Sorry for the blurry picture. Will try to get a better picture tomorrow in daylight.
