I love making zipper pouches like this because they're useful for a wide variety of things. I have one I use as a makeup bag when I travel and another I use to bring my lunch to work.
For this bag, I used the faux chenille fabric I made a few days ago, a pink 9" zipper, and some green scrap fabric for the lining. Cut the fabric the same width as the length of the zipper, including the ends. Make the other dimension the depth you want your bag to be plus extra for the seam allowance.
Start by pinning one piece of your outer material, zipper, and one piece of your lining material material together. The top side of the zipper should face the right side of the outer material.
Once sewn, it should look like the picture above. Pin the outer fabric and lining together, right sides out.
Do the same for the other side of the bag.
Unzip the zipper about halfway and pin the outer fabrics together and the lining fabrics together, right sides in. Starting along the bottom of the lining fabric, stitch along the perimeter of the fabric. Stop sewing a few inches before you get to the starting stitches to leave a hole that the pouch can be turned through. Pink or trim the edges, cutting extra close to the corners to avoid bunching.
Flip your bag right side out and stitch the hole closed either by hand or machine.
Tada! A nice little bag for whatever you want.
