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