Long-Tail Tubular Cast On for 2x2 Ribbing
A variant of the Italian/tubular cast on adapted for 2x2 ribbing. Produces the same rounded, seamless edge as the 1x1 tubular cast on but with the alternating column pattern that pairs with k2, p2 rib.

Setup rows
After casting on with a long-tail or Italian cast on, work two setup rows in a specific pattern: row 1 (RS): k2, slip 1 wyif, p1, repeat; row 2 (WS): slip the knit-on-RS stitches with yarn back, work the others as established. The setup rows establish the column structure.
Why it differs from 1x1
2x2 ribbing has columns of 2 knits and 2 purls. The cast-on column structure must match this, which requires a different setup-row sequence than the 1x1 version.

Best uses
High-quality sweater hems with k2, p2 ribbing. Cuffs and necklines on dressy garments. Any 2x2 ribbed edge where the rounded tubular finish is worth the extra setup time.
Limitations
Only works for 2x2 ribbing. For 3x3 or 4x4, no tubular variant exists — use a stretchy bind off instead. Requires careful attention to the setup row pattern.

Tips
- Practice the setup rows on a swatch — getting the slipped stitches in the correct columns is critical.
- Use a needle one size up for the cast-on row to maintain even tension.
- Block ribbing aggressively to set the rounded edge.
In depth
The 2x2 tubular cast on adapts the rounded tubular edge of the 1x1 method to the column structure of k2, p2 ribbing. The technique requires more careful setup but produces an equally polished result, suitable for the most formal sweater hems and cuffs.
