This is so easy to do. No pattern required. It fits the American Girl Doll and the Australian Girl Doll.
This skirt is basically a straight skirt that can be pulled on.
American Girl Doll
Cut a strip 13" long and as wide as you prefer. I made mine a short skirt so I cut the strip 4 3/4" wide.
Australian Girl Doll
I realised that the Aussie Girl Doll needs the skirt to be fuller and a bit longer. Until I try it out these measurements should work.
Cut a 15" strip 5 1/4" wide. Use the same length ribbing as described in the instructions.
I have used a knit fabric for the skirt. That is why I have a 3/8" hem. I just find it easier than 1/4" on knits. I also tried to get away with my sharp needle for stitching but I had to put in the stretch needle to get the rib to behave.
Sewing knits is not hard. I find that I have to stop with the needle down every 3 or 4 inches to let the fabric flatten out. It does tend to get pushed along in front by the foot.
Overlock the hem edge and turn up 3/8" hem.
Stitch the back seam to make a tube.
Cut a strip of ribbing 1 3/4" wide and 10" long. (Cut 1/2" elastic 10 1/2" long.)
Stitch the ends of the ribbing and fold in half to for a band. (Just overlap the elastic.) Put pins at the centre back and centre front.
Match to centre front and back seam of skirt. Stretch to fit and pin.
The skirt can be worn on the hips to make it longer.
I will be trying out the stretchy band on more gathering and woven fabrics.
