Decorate with your choice of Designer Series Paper--you'll need one 4" x 5-1/4" piece for the inside, another piece that is 4" x 2-1/4" for the bottom front, and one more 4" x 1-1/2" piece for the flap. Adhere these, and then use some Tear and Tape Adhesive on the inside edges to close your pocket. Also adhere the front flap down, creating your pocket for your notecard.
The notecard is 3-1/2" x 3-1/4" (I used Thick Whisper White, with a layer of DSP and a smaller piece of Whisper White on top). Using the smallest oval in the Stitched Shapes framelits, cut a piece of coordinating cardstock, fold it in half, and staple it to the top of your notecard. This is what you'll use to pull out the card out of the pocket.
Thanks to Debbie Henderson for the pocket card tutorial.
