There are a lot of different diaper styles and pocket openings to choose from. My favorite is the modified welt pocket. I love how they look and like that it tucks the insert all the way in and away from baby. This tutorial will show two different ways to center your modified welt pocket so that if you do not have a larger quilting ruler, you will still be able to have a nicely centered welt pocket.

Before you start, assemble needed supplies:

• diaper inner fabric (I am using brown crushed panne)
• 3” x 7” piece of same inner fabric for your modified welt
• pins
• measuring tape, hem gauge, or large quilting ruler
• sewing machine
• marking pen or chalk wheel (for dark colors)

1. Measure to find the center back of your diaper inner fabric.  I use my Dritz chalk wheel for this, as I love how I can just wipe the marks off with water.  To find the centerfold, fold your inner fabric in half and mark a line on the fold.

2. There are two different options for centering your modified welt pocket.

Opt. 1: If using a regular ruler, or hem gauge:

a. Measure from the center 3.5” and make a mark.

b. Measure down from that mark 2” and make a right angle mark, one portion down and one part of the line towards the center.

c. Repeat Steps a and c for the other side of the welt pocket opening, then align the top corners of your 3”x7” piece of fabric with your marks. Make sure the 3” x 7” fabric is right side DOWN on your inner fabric (the right sides of each will face each other).

Opt. 2: If using a large quilting ruler:

a. Line the center dash on your fabric up with the 3.5” mark on your quilting ruler and the top edge of the fabric at the 2” line.

b. Line your 3”x7” piece up with the 0 mark and 7” mark.

3. Use a 1” wide ruler or mark your welt at 1” from the top.

4. Fold the bottom of this piece up to your ruler, effectively in thirds.

5. Pin this piece down.

6. Sew a tight rectangle around the edge that is folded over and the portion that is not.

7. You should now have something like this.

8. Now to cut your welt open.  I like to fold the inner in and give a little snip on the back of the fabric.

9. Then you can fit your scissors in and cut it all the way open.

10. Next pull the piece of your welt that is currently at the top of your diaper down into your opening.

11. Pull the piece that is down up over your opening.

12. Tuck the ends of your welt pocket under.

13. Pin!

14. Make sure you catch the bottom piece of the welt when you are pinning.

15. Sew the end of your modified welt down, making sure to sew past the bottom of your welt by 1/4” or so.  Repeat on the other side.

16. Your front of your diaper inner should now look like this.

17. The back of your diaper inner should look like this. Note how the bottom flap is caught in the sewing, keeping it held down.

You have now sewn a welt pocket!  Now finish your diaper!
