Nintendo DS Pouch Tutorial
I designed this pattern for keeping my DS in. My mum is a BAD influence and after seeing her DS I had to get one for myself. I bought it for the Weight Management game, that was my excuse anyway. I spend most of my time playing Zelda on it.
Requirements:woven fabrics. (2 fat quarters would work well)
Wadding (interfacing would work too)
thread
Ric Rac (optional)
Snaps (or another fastener.. buttons or velcro would also do)
Rotary cutter, mat and rulers make the cutting easy
General sewing bits and pieces
Cutting
Pouch outer two pieces 5 inches by 7 inches
Wadding two pieces 5 inches by 7 inches
Pouch lining two pieces 5 inches by 7 inches
game pockets two pieces 3 inches by 7 inches
pouch flap one piece 5 inches by 6 inches
Making the game pockets
Fold the pocket pieces in half, matching the long ends. Press.

Position the bottom pocket first. the folded edge lines up with the bottom edge of the lining piece. sew across the raw edge with a 1/4 inch seam.

Flip the pocket piece up. Press.

Position the second pocket piece. Line up the raw edge 3/ 8ths away from the top of the first row. Stitch with a 1/4 inch seam.

Flip the second pocket place up. Press. Mark the pockets into sections to create the small game pockets. Measure 2 inches in from each side and draw a chalk line. then draw the center line which is in the middle and creates 1.5 inch pockets in the center. The outer pockets are currently bigger because they include the seam allowance.
You could choose to make similar pockets on the other lining piece.Preparing the pouch outer fabric
Lay your wadding onto the wrong side of your pouch outer pieces. You can baste them into place, I did not. I find wadding tends to cling and is not that hard to handle on such a small project. The wadding and outer are now treated as one piece.

I added some ric rac to the front piece of the pouch outer. You could be very creative here and applique the owners name or add some stitchery.
The pouch Flap
Fold the flap piece in half right sides together. Stitch along the shorter ends.

Turn the flap to the right side. Press and baste with an 8th of an inch seam to the top of the back outer piece. Make sure you center the flap.
Putting it all together
Lay the lining and the outer piece right side together and sew them along the top sides using a 1/4 inch seam. Make sure the pocket openings are positioned towards the outer fabric. You don't want to sew them in upside down. ( Yep done that!)

Open up the pieces. This is what you should have now. I put my lining with the pockets on the back piece as I want my pockets to be at the back of the pouch.

Place the pouch pieces right side together. Carefully match the seam. You want the outer pieces to be together and the linings to be together. Sew a 1/4 inch seam all the way around. Leaving a 4 inch gap at the top of the lining fabrics, this is to allow a hole to turn the pouch through.

To create the flat base of the pouch you sew little triangles ,as in the photo above. Flatten the side seam to the bottom seam and stitch 1/2 an inch from the point. Do this to both the pouch outer and lining fabrics, all four corners.

Turn the pouch through the opening you left in the lining. Close the opening. I folded in the seam allowance and top stitched it closed.

Push the lining into the pouch. Edge stitch around the top of the pouch, to keep the lining in place. I stitched from the inside of the pouch.

Attach your snaps. You could use a button and a button hole. If using velcro it would look better if you added the loop piece to the flap before you folded it, this would hide the stitching.

Now load it up with your games and DS!
