There are many tutorials how to make zippered pouch. Here is the Negligent style :)
You'll need one exterior piece either quilted or with regular iron on interfacing, one zipper and two lining pieces.
Measurements: A = 42cm, B = width of your zipper, mine was 22cm, C = A divided by 2 + seam allowance, 21+1= 22cm
Place your zipper teeth facing right side of your exterior piece and add lining wrong side facing up. Not pictured but right side of exterior and lining are facing each other.
Tip: If you are beginner in pouch making I'll recommend you use solid where there is no need to figure out wrong or right side.
Use your zipper foot to attach the zipper. I sew the zipper open. Once I get closer to the zipper pull, I'll lift the foot, slide the zipper pull out of the way and finish the last bit of zipper.
Place your second lining piece right side facing up, zipper teeth should face up as well and exterior piece is right sides together which means the wrong side is facing up. See the picture above.
I sew this side of zipper the same way. Sew it open, slide the zipper pull out of the way and finish.
This is optional step and I only do it if I will not topstitch the whole pouch once finished. I either topstitch or zigzag lining piece. Make sure you only sew on lining and zipper edge. This should be only visible inside the pouch.
I do that on both sides. Once again, make sure you do not sew over exterior piece!
This is what your piece should look like. Exterior piece if forming a loop and lining pieces are over lapping.
Important: Open up zipper before begging the pouch assembly!
I prefer to make turning gap on the side. If you prefer to have it on bottom, make it on the bottom. Otherwise follow the red lines and
sew the pieces together.
Box the corner on exterior piece. Make sure you have the seam in the middle. Mine was 8cm that means 4cm on the left side, 4cm on the right side. Also make sure that you make both corners the same size. Trim.
Box the corners on lining as well. Put a pin through the seams to make them face each other.
Use your ruler and mark the line. See 4cm to each side.
Once you finish, it should look like in picture above. Turn inside out through opening gap.
Close opening gap by machine or hand. Up to you.
Iron well and you are done!
There are many options for exterior piece. Make it out of selvedges, use FMQ piece or use other technique. The advantage of using one exterior piece is that you end up with no seam at the bottom.
You can also make the
open wide zippered pouch with one exterior piece. Just use longer zipper and check out the different way of attaching zipper.
