Lay the bag body pieces out one on top of the other. Measure 13” down and 2” in and cut the pieces out on either side. *If you’re using batting repeat this step with the batting.* That will create the FLAP PIECE. Then measure 1.5” down and 1.5” in from the top corners of the LINING fabric and mark it. Install the magnetic snaps on both sides there using the package’s instructions. (Make sure you only poke through the lining fabric!)
Fold the bag up like the picture above (you should still have both layers of fabric). Mark where the snaps hit the front of the bag and install the other end of your snaps there on the OUTER fabric.
Put the pocket piece on the lining piece on the bottom part, not the FLAP PIECE. You can center it if you like but you don’t have to. I made mine so that one side was higher (and the pocket therefor deeper) than the other. Pin the pocket piece on. Now fold the lining piece so that the bottom of the bag body piece meets the bottom of the flap piece and press. Your crease is your guideline for the image above. Measure one inch to the right of the center and one inch to the left of the center and mark the pocket piece all the way across with your chalk. Then mark where you want to separate your pockets. Sew on the lines you marked like the diagram above.
Fold the corners down and press. Take a ruler and measure 2 inches across the corner and mark that with your chalk. You can do one of two things here. You can either serge across that line or simply sew and leave the corner on, it’s up to you. When you’re done it should look like this:
And make sure you take a picture and send it to me 🙂
