I find these little zippy pouches to be a most gratifying project. Very simple, quick, and a fun way to use up cute scraps of fabric. Since I plan on making more, and you might like to also, here is a simple tutorial to keep the steps right at hand. Let's get started!
You will need 4 pieces of fabric (two for outside, two for lining) and a zipper of whatever length your cut fabric is. (I love thrifting vinyl zippers. Nice and cheap, and you can cut them to size!)
Next, sandwich a right-side up zipper with a right-side up lining and a right-side down outer. Stitch across, close to zipper.
Flip fabrics so zipper selvedge is now inside. Repeat these two steps on the other side.
Looking good so far? If you'd like to top stitch close to the zipper, now's the time. You don't have to, just if you like the tailored look.
Flip fabrics so right-sides face each other, outer to outer, lining to lining. (Don't forget to un-zip the zipper at least halfway so you can turn it once it is all stitched!) Pin around the edges, turning zipper teeth and seams towards the lining.
Stitch all around the edges (about 1/4 inch) leaving a 2-4 inch opening at the bottom of the lining. Clip corners.
Turn so that right-side fabrics are now out. Stitch lining opening closed. A slip stitch by hand is always the prettiest, but I usually just run a machine stitch all the way down, very close to the seam.
Tuck the lining into the shell, give it a good press with a hot iron, and Voila! A nice little zippy pouch for you.
