Step 1: Use a DVD case to wind the yarn around.
Prepare a DVD case and a spool of yarn. Then wrap the yarn around the DVD case. There are two sides of a DVD case: a smooth side, and a notched one, where the case opens. Start at the notched side, wind the yarn towards the DVD case’s center. Make sure to wind the yarn fairly tight and close together so that no yarn is overlapping and there are no gaps in yarn.
Keep winding the yarn up to 3-3.5 inches across the DVD. Push the yarn together to fill in any gaps in the yarn.
If you find it difficult to keep the yarn in place with your fingers only, you can use a piece of scotch tape to tape down the end of the yarn.
Step 2: Tape off the yarn.
When your yarn is wound around the DVD case, take two long pieces of scotch tape. Use these tapes on the smooth side of the DVD case. Just underneath the smooth side, on the front and the back of the DVD case, tape down the yarn. The yarn should be securely taped to the DVD case.
Step 3: Cut the yarn.
Slip a pair of scissors underneath the notched edge of the DVD case and use them to cut through the yarn on this side of the DVD case. After that, un-tape the yarn on the smooth side of the DVD case, keep the tape attached securely to the yarn. You can see something of a wig forming. The tape will create a mark where the doll’s part will be. There may be strands of loose yarn which come off either side this part.
If you have difficulty cutting the yarn, try using a sharper pair of scissors. You had better use sewing scissors than normal craft ones if you don’t want the hair of your doll to look uneven.
