Pre-wash and dry all fabric. This is not my favorite diaper. I don’t really like the way these diapers look when they are on.
The flaps look funny. I like the fitted diaper with Aplix the best!

This is the template I use to cut out this diaper.I got this template by tracing one of my favorite  diapers and adjusting it a little according to my taste.  This is the easy way to do it.
This pattern measures:
20″ long –
9 1/2″ at the center –
12 1/2″ wide at the front wings –
20 1/2″ wide at the back wings.

This pattern fits a 30 LB toddler with room to spare. Please see the diaper dimension page for more info.

Lay your pattern on two layers of flannel. In this picture I used one white and one yellow.
The yellow will be the outside of the diaper.
cutting fabric
Next, cut out the soaker pad.  I make mine with 2 layers of terry cloth in-between two layers of flannel.  This pad measures 6″ wide x 16″ long.  For the next size down (medium) the pad will measure 5 1/2″ wide x 14″ long.  Again, play around with these measurements, till you get the perfect fit. soaker pad
Serge or overlock the pad all the way around.  I straight stitch to make a nice rectangle and then I overlock the edges. Be careful not to the let fabric crawl too much.  A walking foot is great for this. edging the soaker pad
Place the pad between the two layers right in the center soaker pad placement
Straight stitch the pad between the layers, stitch all layers together.  Be careful about those little folds you see  in this picture. This is a result of the fabric crawling and puckering.  A walking foot is great for this too. sewing in the soaker pad
Elastic length with vary depending on the type of elastic you use.  I use soft stretch elastic.  Determine where you want your elastic to start and tack it down.  Stretch the elastic fairly tight  and zigzag stitch the elastic to the diaper. When you get to the end point, backstitch and cut the elastic. sewing the elastic
Sew elastic on the back, front and legs. I sew  in about 1 inch so I will have a nice ruffle. Update: I don’t like the 1 inch ruffle. It’s too hard to keep tucked into the cover. I would suggest making a smaller ruffle or turning the diaper (see the fitted diaper with Aplix for instructions). elastic placement
Serge or overedge the two layers together.  Pulling the layer with the elastic to fit.
edgeing the diaper
Your almost done!  Now is the time to decide if you want snaps or Velcro.  At this point, I would wrap the diaper around your child and determine where the snaps/Velcro should go.  I put a snap at the top of the flap and at the bottom of the flap.  I only do one row of snaps. As my child grows, I will add another snap if needed.  I use size 16 snaps, but any size will do. Adding Velcro at this point might be tricky as you would have to sew through the soaker pad. Maybe add the Velcro before you sew the two layers together. This is also a great diaper to pin. almost done
I didn’t have any snaps at the time to put on the yellow diaper, so I thought I’d show one of my previous diapers. When you make colorful diapers like this one, be careful when you wash. green diaper
