I always wanted to make one and tonight I did, you can find a version of the directions on Split Coast Stampers web site under: Flower Pot Pocket Card tutorial
Step 1 - base card is 9" x 3 1/2"
Step 2 - scored at 3 1/2" at one end, turn around and score the other end at 2"
Step 3 - Take a paper trimmer to the 2" end to create a scallop edge. (I used my EK Success border punch)
Step 4 - fold like an according and ink as you like
Step 5 - cut the pull up card piece at 4 1/4" x 2 1/4"
Step 6 - while the piece is inserted - create your blooms as you like and adhere to the top of the card piece that pokes out of the pot - do not glue your blooms to the pot.
