A stitch from S.F.A. Caulfeild’s Dictionary of Needlework, p. 129, rewritten in modern terms.
This is a pretty stitch for handkerchiefs, shawls, etc, or as a stripe for a blanket. Cast on a foundation chain the length required. First row–raise all the loops as in Tricot, and work back very loosely. Second, or pattern row–keep the wool to the front of the work, take up the little stitch at the top of the long loop without drawing the wool through, put the hook from teh back of the work between the next two loops, draw the wool through to the back across the long loop, pass the stitch just formed into the one above the long loop without taking the wool on the hook again, take up the next small stitch above a long loop (the wools should be still in front), insert the hook from the back between the next two long loops, draw the wool to the back, and pass this stitch into the last raised, continue to the end, work back in the usual way very loosely, and repeat the second row.
Foundation row: Work one row of Tunisian Simple Stitch (TSS) as usual on any number of stitches. Work back as usual, but loosely.
*With yarn in front, insert hook into the chain loop directly above the second vertical bar. Do not pull a loop through yet.
