18" Doll skirt tutorial...

First, sew your four  7" x 7" squares together to form a tube, then press the seams open.

Then turn up the raw edge of hem 1/4"- using your sewing gage. Iron.

Fold it up an additional 1/4" and press again. Pin in place and stitch.

(Bad example... I rarely use pins. Sorry!)

Here the finished hem is shown. Next turn the waist under 1/4" inch as well and iron.

Next- use your sewing gage to fold waist under an additional 5/8" Iron and pin into place.

Sew as shown. This will create a casing for the elastic waist. Leave a small opening to add elastic in.

Next, measure your dolls waist and subtract an inch.

Cut elastic to that measurement. Add safety pins to each end. This will help you insert and pull the elastic through the casing.

When you have the elastic in, remove the safety pins and stitch the ends of the elastic together using a zig zag stitch. Then pull the casing tight and machine stitch the opening closed.

You are done! Try it on your doll and admire your work!
