With all the seams sewn and trimmed it is time to turn your baby doll sleeper right side out. If you are working on miniature doll clothes, use or to carefully turn the sleeper right side out through the neck opening. Take care not to stretch the neck too much.
To finish the main sewing of the baby doll sleeper, sew across the base of the legs matching the lines you drew for your doll feet. Make sure you avoid making a tight point at the toe end of the foot, angle your stitching up from the bottom seam to make a slight boxed end at the tip of the foot. Trim the base of the legs and feet to match your seam allowance on the rest of your sleeper. Use fray check to seal the fabric edges if it doesn't make your fabric too stiff.
To finish the closure on your baby doll sleeper you can add a strip of velcro tape, small buttons or snaps, depending on the size of your doll. For larger dolls, small zippers are also available.
The next step in assembling your baby doll sleeper is to sew the side seams from the underarm down to the base of the upper leg seam. Use small back stitches and keep your tension uniform. Remember that the front fabric piece is wider than the back piece, so match the edges of the fabric, don't worry about the extra in the middle of the front.
