How I Converted Taylor’s Flats to Fitteds

What you’ll need to make 1 fitted diaper:
2 birdseye flat diapers
An old T-shirt
10 inches of polybraid elastic; either 1/4 or 3/8 inch will work.  I buy mine from Verybaby and Wazoodle.
Other supplies needed:
Rita’s Rump Pocket Pattern or other preferred pattern
Sewing machine
Coordinating thread
I recommend watching this video to understand the nature of diaper sewing…

  • Take pattern and use it to cut out a layer from both a flat diaper and the t-shirt.  Be sure to mark the spots where the elastic is to be tacked on.

  • Take the remaining flat diaper, fold in half and cut the rough edges off.  This will make serging a bit easier.  Fold diaper together so that it resembles a soaker.  Serge around the edges. 
  • Sew the soaker onto the t-shirt diaper layer with either the zig zag or straight line stitch staying about 1/4” from the edge.  Position it in the crotch area so that it provides the most absorbency where needed.  This may vary by baby.   
  • Cut out two pieces of elastic, approx. 5” each.  On the t-shirt diaper layer, tack elastic onto each marked end of leg areas with sewing machine.  I do this by sewing forwards and backwards multiple times.  Leave about a 1/4” inseam to leave room for serging the edges.  I sew the elastic onto the side where the soaker is visible.  If you are unsure how to do this, watch the diaper sewing video above.
  • Put the the birdseye and t-shirt layer together (soaker and elastic on the inside), and serge around the edges with coordinating thread, paying attention not to serge over the elastic.  I usually start on an inside wing so that my starting point is hidden by the outer wing. 
  • Encase the elastic with sewing machine.  To do this, start where elastic is tacked onto diaper and sew approx. 1 inch from the edge of the diaper.  Stretch the diaper so that the elastic is against the inner edge of the diaper and sew carefully down to other tacked end, making sure not to sew over the elastic.  Refer back to the video above if you are having difficulty with this step. 
Your diaper is done!  All you need to do now and cut off the extra thread and tie off or hide the serged tail in the seam.
My favorite part about these diapers is that you don’t need to apply snaps or aplix/touch tape making them a better fit for any baby.  I use a snappi to close them, but you can also use pins.  If you prefer to add an enclosure, then go for it!
This diaper needs a cover.

*For smaller babies simply fold down the front and/or back of diaper. 
If you don’t have a serger, never fear!  These instructions can easily be adapted to accommodate a sewing machine with a little creative thinking.  
One way would be to use the zig zag stitch all the way around the diaper at the very edge, configuring the settings so that the zig zags are wide, yet close together.
