Purlbed

Short rows (partial knitting) › Knitting in sections

Partially knitted sections (leaning columns)

Vertical columns that lean diagonally and wave, like a braid or woven tape. Rows of shaping eyelets sit between the columns (bigger eyelets mean more rows per group). Lean direction follows carriage direction. Stretched it looks like brickwork; relaxed it ripples.

Steps

  1. COR start:
  2. A: R rows → COR.
  3. A+B: R' rows → COR.
  4. A+B+C: 1 row → COL.
  5. B+C: R'−1 rows → COR.
  6. Continue to the last group, adding a row if needed to end COL.
  7. Mirror back to the right.
  8. Repeat.

The full card

What it looks like
Vertical columns that lean diagonally and wave, like a braid or woven tape. Rows of shaping eyelets sit between the columns (bigger eyelets mean more rows per group). Lean direction follows carriage direction. Stretched it looks like brickwork; relaxed it ripples.
How it behaves
Vertical undulating columns, a corrugated relief. Medium.
How it works
Divide the bed into groups A, B, C… numbered from the carriage side. Traverse across: knit a pair of groups for many rows, then 1 row taking in the next group, then drop the previous one and knit the new pair for many rows. Repeat to the far side, then traverse back. Variation: graduated sections, where both group width and rows decrease together (e.g. 8n/12r → 4n/4r, removing alternating edge stitches by transfer) for a lacy, hole-dominated look.
Machines
Single bed, hold. Fast to knit. Decreasing groups need a transfer tool.
Parameters
group size g (5–8); rows per pair (6–12); bridging single rows (1); number of groups (≈6–7); tension 6–8 on 4-ply cotton.
Steps
COR start: 1) A: R rows → COR. 2) A+B: R' rows → COR. 3) A+B+C: 1 row → COL. 4) B+C: R'−1 rows → COR. 5) Continue to the last group, adding a row if needed to end COL. 6) Mirror back to the right. 7) Repeat.
Charting
Group letters across the top, right to left (A at the carriage start). Dashed vertical lines between groups. Dark shade for multi-row blocks, light shade for single-row bridging. Arrows at the row ends. Shorthand COR/COL = carriage on right/left.
Limits and common problems
Lost position in the sequence is the most common error, so count eyelets from the cast-on. Knitting the end groups alone makes the selvedges loose; pair them with the neighbour instead.
Combines with
stripes every 2 full traverses; elastic or shirring stripes; pk-sections-twisted; pk-sections-bridged.
Pieces and assembly
Self-structured panels; can be pinned and steamed to set.
