Purlbed

Tuck and slip › Mosaic

Mosaic / maze via slip or tuck with 2-row stripes

Face: geometric two-colour motifs that look like Fair Isle but have no long floats; slightly textured. Purl side: horizontal stripes with short floats (slip) or bumpy tuck loops. The colour changes every 2 rows.

Steps

  1. Draw the motif; each chart line = 2 rows.
  2. Convert to a card: odd rows mostly knit, even rows single marks.
  3. Selection row (direction per card start,).
  4. Slip (or tuck) both ways; change colour every 2 rows.

The full card

What it looks like
Face: geometric two-colour motifs that look like Fair Isle but have no long floats; slightly textured. Purl side: horizontal stripes with short floats (slip) or bumpy tuck loops.
How it behaves
Single layer, narrower and denser (tuck: wider and shorter). Slip edges curl more.
How it works
The colour changes every 2 rows. Non-selected needles slip (or tuck) while the other colour knits, so the previous colour's stitch is pulled up and appears in the new colour's row.
Machines
KH-821 single bed: PART (slip) or TUCK buttons + card. A colour changer is optional (manual changes at the edge). Dubied: tuck/slip per pass on high vs low butts only, so only fixed geometric mosaics (see the next card).
Parameters
slip ≤2 adjacent unselected stitches, tuck ≤1 per row (classic rules); even design height; 2 rows of design height ≈ 1 stitch width; max ~4 tuck rows stacked.
Steps
1) Draw the motif; each chart line = 2 rows. 2) Convert to a card: odd rows mostly knit, even rows single marks. 3) Selection row (direction per card start,). 4) Slip (or tuck) both ways; change colour every 2 rows.
Charting
Mosaic chart (each cell = 1 stitch × 2 rows, colour of that row pair). The separate card chart: black = knit/selected, white = slip/tuck.
Limits and common problems
Wrong preselection side shifts the colours. Too thick a yarn with stacked tucks.
