How to Sew a Zipper Bag

You will need the following to learn how to sew a zipper bag:
2 pieces of 8x12 inch material
8x12 inch interfacing
7 inch zipper




See below for a video on sewing zippers.

Step 1 for Intermediate Lesson 3

Layer the interfacing and one 8x 12 rectangle material on top of each other so the right side is visible.



Iron together. Some interfacing is fused to the material with an iron,  some has to be sewn together. Read the instructions that come with the interfacing to determine. Place the other piece of material on top of the interfacing, right side up, so you have a double sided piece of material. Pin in middle to secure together. Set aside until the next lesson, where you will learn about adding zippers.

Fold in half. Pin zipper to the top edge as shown in the picture.



Unzip the zipper half way. Start to sew and then move the zipper up to the top and continue sewing. Pin zipper to opposite side.



Sew. Now pin sides and sew each side. Unzip zipper and turn right
side out.
