You know how a knit 1, purl 1 rib is nice and stretchy except for that taut line along the cast on edge? The Long Tail Tubular Cast On is designed to fix that problem! Once you try this cast on, you will appreciate how magical it is. The technique is surprisingly simple and very similar to the traditional long tail cast on, but it creates a beautiful, elastic edge, perfect for hats, socks, cuffs or anywhere you need a little give! We used this cast on technique in our Classic Cuffed Hat project.
