Two-colour tuck

Textured tuck fabric where the second colour shows as broken vertical streaks or dots on a striped ground. On the purl side, colour pools in the tuck loops. Viewed as a pattern it looks like a "mosaic" with soft, blurred edges. TUCK buttons with K.C.

The full card

What it looks like
Textured tuck fabric where the second colour shows as broken vertical streaks or dots on a striped ground. On the purl side, colour pools in the tuck loops. Viewed as a pattern it looks like a "mosaic" with soft, blurred edges.
How it behaves
As tuck; slightly more compressed.
How it works
TUCK buttons with K.C. The yarn in feeder A is exchanged every 2 rows (both colours alternate in A, B is not used). Tucked loops from colour 1 are pulled up into colour 2 rows, carrying colour vertically.
Machines
KH-821 yes (hand change every 2 rows). A colour changer helps if compatible [unverified for KH-820].
Parameters
Colour change every 2 rows (the English manual phrases this as changing "every third row", i.e. at the start of row 3). Same tuck limits apply. 1. Thread both yarns through the tension unit. 2. Put one in feeder A; clip the other on the yarn clip. 3. Knit 2 rows; park the first yarn at the needle bed end and thread the second into A. 4. Repeat every 2 rows.
Card design rules
As tuck. Design in 2-row bands: each colour's 2 rows usually share the same selection, so on the card, pairs of identical rows are common.
Charting
■/□ as tuck, plus a colour band column (A1/A2 alternating every 2 rows).
Limits and common problems
As tuck; also tangled yarns at the edge from frequent changes.
Combines with
two-colour slip, mosaic designs.
