So, I was going through my room, and I found this soft plastic container that some camis came in. Here's how it got used:

rubber ducky wallet (sorry-I didn't get a shot of the outside)


Materials:
cardstock
velcro
thin, soft plastic. (try doubled over packing tape, or sheet protecter plastic)
thin cotton fabric of two types
interfacing
cut:
Outer-
9"x9"
6 1/2" x 3 1/2"
Lining-
9"x9"
6 1/2" x 4"
3 1/2" x 4 1/2"
Interfacing:
9" x 9"
3 1/2" x 4 1/2"
Note: AS YOU SEW, TRIM ALL THREADS IMMEDIATELY.
1. Cut all fabric pieces out and iron. Attach interfacing to large outer piece (9x9)
and to the smallest lining piece.

2. Cut your cardstock into the following sizes:
-2 1/2" x 3 3/4"
-5 1/2" x 2 1/2"
-5 1/2" x 3"

3. Center the smallest piece of cardstock on the back of your interfaced lining piece. Iron the edges of your fabric in, using the cardstock as the template. Remove the piece of cardstock, and spritz the folds with water, then iron again. If the corner fabric sticks out, trim it. Repeat this process for each of the pockets.


4. Topstitch around your smallest rectangle, about 1/8" in from the edges. Trim your fabric along the seams. Set aside. Top stitch 1/8" in from the edge for one of the long sides on each pocket.
5. Draw a rectangle 1/2" in from each side of the license holder (smallest rectangle). Cut a rectangle out of this piece, a little more than 1/4" smaller on every side than the rectangle you've just drawn. Carefully cut the corners diagonally until you just meet the pencil lines. Fold back edges and iron.

6. Cut your plastic to the same size as your template. Topstitch around the cutout, with the plastic on the bottom of the rectangle. As you stitch, be careful not to pull on the cloth. Use your plastic piece as a guide for where the edges should be. Trim back the plastic. If it doesn't lie flat, DO NOT IRON. Instead, crush it between a couple of heavy books and let it sit while you work on the next part.

7. With right sides together, sew your two large pieces with a 1/4" seam allowance, leaving a 3" gap on the side. Double stitch where you start and finish. If your fabric has a right side up, make sure the gap is on the side, not the top/bottom. Cut the corners, then trim the seams, everywhere except the gap.

8. Turn this inside out and iron flat. With the outer fabric on the bottom, fold the fabric up, so that 1/4" of the lining is showing at the top (this can be seen on the first finished pictures). Iron this flat, spritzing water here if needed.
9. Open the fold. On the smaller 1/2, Attach your license holder, lining the edges up with the left/top edge of the fabric. Follow the previous topstitching. DO NOT SEW DOWN THE INNER LENGTH. Pick up your large pocket. Hold the unsewn edge parallell to the fold, about 1/2" up. Line the right edge of the pocket directly up with the right edge of the main piece. Set aside.

10. Now measure 11/4" up from the bottom of the small pocket, and 1/4" in from the right side. This marks the bottom right corner of your velcro piece. Attach the hooked velcro here, stitching all the way around twice. Line up the bottom edge of your pocket 1/4" from the fold and sew down, again using about 1/8" seam allowance. Sew 1/8" away from the left side of the pockets.
Turn the wallet around, so that the license holder is in the bottom right corner. Measure up 1 1/2" from the fold, and 1 1/2" from the right side. This is the bottom right corner of your other velcro piece. If you want, topstich the top edges of the wallet now.
Fold the fabric so that the edges of the pockets meet. Mark the center line. Sew along the center line, stitching only the pockets. Sew another line 1/8" away on either side (you now have three lines).

11. Fold in 1/2. Stitch along the bottom of the wallet, 1/8" away from the edge. Now starting at the bottom of the wallet, stitch up both sides, 1/8" away from the edge. On the right side, be sure that you're sewing down your pockets now. DONE! Do not iron the wallet flat-Instead, put your cards in it and crush it beneath some books. Stand on it for good measure.

Finally. I swear, this isn't nearly as complicated as I've made it sound. Let me know if anything is hard to understand. I don't care if anybody sells these wallets, but I ask that if anyone figures out improvements on my design, please share them.
