All the loops of the stitches in every course are pulled to the back of the fabric.
- A right and wrong side.
- Reduced stability.
- Light to medium weight.
- Curled edges.

Double knit jersey
Knitted on a machine that uses two sets of needles to make a double thickness of fabric.

- Can be plain or patterned.
- Less stretchy than single knits.
- Doesn't curl at the edges.
- More easy care than single knits.
