Bodyshell has been improved with double stitch welded monocoque chassis with front and rear strut tower brace bars.

A double square stitch (or triple) can be made using four strings, thus doubling the size of the keychain made.

To create a picot in tatting, the first half of a double stitch is made.

The resulting picot is then anchored between two double stitches.

It is also possible to anchor the picot between the two halves of a full double stitch.

Basic granny squares alternate sets of double stitches and chain stitches.

The skin is first sewn with fur inside and with only single minimal (double stitch) seam.

An additional leather band is then stitched on top of double stitch to create an airtight seal on the bag.

There are 108 double stitches on a baseball (which some people call 216 stitches).

The size of the space is determined by the number of chain stitches between each double stitch.
