Tricot Ecossais

A stitch from S.F.A. Caulfeild's Dictionary of Needlework, pp. 128-129, rewritten in modern terms.

Abbreviations:

• YO = Yarn Over
• TSS = Tunisian Simple Stitch
• st(s) = stitch, or stitches

Chain a multiple of 3 stitches, plus 1.

1: Sk 1 chain. *YO. Pick up one st in each of the next 3 chains. Pinch the YO in the hand not holding the hook and pull the last three sts on the hook through the YO. (This leaves the three sts on the hook.)* Return as usual.
2: Skip the first vertical bar. *YO. 3 TSS. Pull the last 3 sts on the hook through the YO.* Return as usual.
This is very similar to some maneuvers from knitting, like passing a slipped stitch over another one.

(I expect the name has very little to do with the stitch's national origin - the name means Scottish knitting in French.)

Josephine Tricot Stitch

A stitch from S.F.A. Caulfeild's Dictionary of Needlework, p. 130, rewritten in modern terms.

This stitch has fewer similarities to knitting than the other Tunisian crochet stitches I've tried. It makes a nice mesh.

Special abbreviation:

JTS: Insert hook in a stitch, pull a loop through, and chain one.
Repeat in the same stitch. Pull a third loop through the same stitch,
and then pull a loop through the last three stitches on the hook.

Original version (but with modern terms):
Start by making a chain the length you want, plus three.

Row 1: JTS in the fourth chain from the hook, repeat in every chain to
the end. Return row as usual.
Row 2: Chain 2, then work a JTS in each chain space. Return row as usual.
Repeat row 2 as desired.

If you find that the start of the row is a little too tall, try doing
1 chain instead of 2.

I found that I could get a version that draped more softly if I added
some extra chains, like this:

Variation:

Start by making a chain with an even number of stitches, plus one.

Row 1: JTS in the third chain from the hook, repeat in every other
chain to the end. Return row: Chain 1. *Chain 1, pull a loop through
the first 2 stitches on the hook.* Chain 1.
Row 2: Chain 1, then work a JTS in each chain space. Return row: Chain
1. *Chain 1, pull a loop through the first 2 stitches on the hook.*
Chain 1.
Repeat row 2 as desired.

This stitch pattern lends itself well to being fringed. Omit the last
return row and knot two pieces of yarn through each stitch.
