This vintage jumper pattern is worked in Birleen Tricot crochet, a technique that is essentially
the same as Tunisian crochet. Using a long crochet hook, multiple loops are held on the hook
at once.
Each row is completed in two parts: a forward pass where loops are picked up across the row,
followed by a return pass where the loops are worked off the hook. This method keeps the right
side of the work facing you and creates a firm, textured fabric.
The pattern uses Carnell Superfine wool (no references found), and is designed to fit about a
34-inch bust. The finished jumper measures about 19 inches from shoulder to lower edge,
round garment at underarms, 35-inches, and 5-inch sleeve seams.
Materials include 6 oz (170 g) white yarn and 1 oz (29 g) navy, a Carnell blanket needle
(substitute this with the correct size Tunisian crochet hook, to match the tension), 6 press
fasteners, 10 inches of silk bias binding.
Tension: Approximately 5 stitches and 8 courses to 1 inch.
This is a quick and satisfying vintage project that showcases the distinctive texture of
Birleen Tricot (Tunisian-style) crochet.
