Take your Sandie and place it on top of three layers of flannel or paper
 (for a template). Pull the Sandie tight and trace around the diaper on
 one side only.  Using stretch terry is better than using flannel for this
 diaper. Stretch terry has more give. If you are using flannel I would
 increase the measurements a tad so the fit is a little better.   

Cut on the line and fold it in half and cut the rest of the diaper/template
 out 

Doing it this way makes both sides even.  If you trace all the way
 around the diaper, you will be sure to have a lopsided diaper.  Both
 sides should be the same. 

Here's your diaper template.  This is a toddler size diaper, the
 measurements are:  

16 1/2" across the back
8"         in the middle
11"       across the front
19"       long

Next cut out your soaker pad.  This pad measures roughly 5
 1/2"x15". you can make the soaker any thickness you like.  On this
 diaper  I made, I used 4 layers of stretch terry. It seems to be the
 same thickness as the *real*   Mother-eeez diaper. 

Serge all the way around your soaker

Sew the soaker pad on to *two* layers of flannel.  Centering it in the
 middle.

Next, take your *real* diaper and mark where to place the elastic.

I don't measure my elastic. I start sewing it at the dot and stretch as I
 sew, stopping at the second dot and cut the elastic. It's easier to do it
 this way than it is to measure the elastic 

Sew elastic on each leg, the front and the back.  Stretching it tight as
 you sew it on. 

This is the top 2 layers with the soaker pad and the elastic sewn in. 

Don't forget your label!! Sew your homemade label on the front corner f
 the soaker pad stitches. Do this *before* you sew on the bottom
 layer. 

Sew the top layer of flannel on to the rest of the diaper.  Serging all the
 way around

Sew a straight stitch on each leg in between the soaker and the
 elastic.  

This is the inside of the diaper 

and this is the outside of the diaper.

Figure out snap placement by looking at the original diaper.

Hammer snaps in place and your "Mother-Eeez" Sandie is complete!

This picture looks a little lopsided, but it's not in real life.  It fits perfect
!! However, it would be better with stretch terry instead of flannel.
