How To Sew Flat Diapers?

  1. Flat diapers can range from a 27" square to a rectangle 18"x36" to 18"x45".

  2. Diapers from different widths (1 yard length)

  • 27"

    • Can make a flat diaper 27" square. If you buy 3 yards you will get four 27" square diapers exactly. You could make two prefolds by cutting 2 pieces 27" x 18". Folded in half will yield a 2 layer diaper 13.5" x 18". An inner terry layer would be desirable.

    • You could get four 2-layer newborn sized diapers 9"x13.5" but this is kind of small.

  • 36"

    • You can make 2 flat diapers 18"x36". Fold these to make two 3-layer prefolds 12"x18".

    • You could make two 2layer newborn diapers 9"x12" but this is also kind of small.

  • 45"

    • Can yield 2 flat diapers 18"x45". Can make four 2-layer prefold 11"x18". Add inner terry layer if desired. Can also make 2 thicker prefolds 13"x18

    • ' with extra center panel if folded this way: fold in thirds, first left side in 13", then right side in only 10" instead of the whole 13". Then fold the extra material back over to the right another 5", then to the left the remaining 5". Pin to secure center panel.

    • Stitch either side of panel, bind top and bottom.

    • Can make four 2-layer newborn diapers with center padding approximately 11"x14".

    • Cut 4 pieces 22.5"x18".

    • Fold in half.

    • Cut off extra 4 inches and center inside the folded diaper.
