Print the pattern (Actual size) and assemble as directed. The 19 inch size will require 1/4 yard of fabric, and less for the smaller sizes. I recommend using upcycled materials for the best economy. The simplest way to determine the amount of fabric required, would be to print the pattern and take it with you when sourcing fabric.
Notions required: 1/4″ elastic and a snap (or button, or clasp). The amount of elastic required will depend on the thickness of the doll thigh (plus 1/2′ to 1″)
Seam Allowance: 5/8″ for the 19″ and 15″ rompers. 1/4″ for the smaller sizes.
Sew the front seam of the facing.
With right sides together, sew the front facing to the front of the romper. For best results, press the seams open before placing.
Clip the curved seams, but not too close! Do not clip the stitching.
Turn the facing right side out and press well. Set aside.
Back of Romper
Place the facings on the back pieces with right sides facing.
Sew the neck and armholes together, then clip the curves.
Turn right side out and press well.
Place the back pieces together with right sides facing and sew the crotch area.
Open the back and on the wrong side, press the back opening as shown. Sew the opening closed on 3 sides, as shown. The folded opening should be even with the crotch seam allowance.
With right sides facing, sew the romper front to the back at the shoulders and sides.
Fold the garment in half and press up 5/8″ of the leg openings. Sew the leg openings, leaving a casing for the elastic. For this tutorial, I used a 1/4″ width elastic. Be sure there is enough space for the width of elastic you have chosen to use for this project, if other than 1/4″ width is used.
Measure the doll thigh for the elastic. Add 1/2″-1″ to accommodate the thigh and seam allowance. Insert the elastic into the casing. As you are inserting the elastic, make sure it does not pull into the casing and disappear. Take care to pin the elastic end before pulling all the way through, as shown.
Guide the elastic into casings on both legs and pin into place. Sew the crotch area.
Turn right side out and attach the closure. A snap, button or hook and eye all make a good closure.
This romper pattern is an adaptation of this pattern from 1973.
