Watch us wind a bobbin (30 seconds).
|First, manually capture the end of the yarn|
|Next, build up the shoulder of the left side of the bobbin|
|Course right, moving to the other end|
|Build up the right shoulder|
| Finally, fill in the middle with a slight bulge in the center.
The yarn at the middle of the bobbin should be proud
— slightly higher that the yarn on either side, but below the plastic ends.
