This is a mini tutorial written and photographed by Doll Artist Sue Sizemore.  This is shown on Sue's  latest large doll, Alexandra, which is about 3 feet 7 inches tall.

Step 1: Attaching skull cap:

First,  cut out  a round circle of craft velour in matching hair color the close to the size of her head. Folded and tuck  it to form it to the head. About four little  pinned tucks. Quick stitches were made throughout the fabric and into the doll head to make it permanent.

Trim the "hairline" around the forehead and the around the ears.

I like to use meter thread and tack every two inches using two to three stitches each thru the cap and into the doll's head along the wefting.

 Step 3:

This picture shows starting  the second row of Spiraling curls up and  around head while tack sewing it. .

 

Step 4:

This picture shows the back of the head and I'm still spiraling the weft around.

This picture shows the back of head, nearly done! At this point I begin  using smaller 4 inch pieces of weft  to fill in the bare spot wit a two inch.  

Wefted Spring Curls on wig cap complete!

Alexandra, she is 3' 7" tall, made form Craft Velour in the color Baby Bear Beige. She has  wired arms and fingers and a  weighted torso. 1-76" weft of spring curls from clothdollsupply.com were used to create her full head of curls. 

Alexandra has wired arms and fingers, and weighted torso. Three wefts of spring curls from clothdollsupply.com made this very full head of curls on this large doll. She wears an antique Victorian child's dress, tights and a  gold locket.
