1, cut, cut a piece of rectangle 22 cm long and 10 cm wide, a 20 cm zipper.

2, first sew both sides of the zipper on both sides of the long. Take care to align them.

3, then turn the bag upside down and sew on the other two sides.

4, then fold the bag back over. So a pen bag is done, put a few pens in it and try to see.

5, the location of the zipper, can be placed on the side, more convenient to use.

6, you can also add a small handle, easy to hang up. Clip a strip of cloth when sewing the side seams, and finally a good-looking quicksand pencil bag is finished.
