How the Shaping Schedule Builder Works
The Shaping Schedule Builder works in 4 steps.
- 1
Enter the rule
Write the shaping rule in the notes box with the starting stitch count, for example "Start 40 sts; inc 1 each end every 6th row 5 times".
- 2
Build the schedule
List each shaping row with its new stitch count: "R6: 42, R12: 44, R18: 46, R24: 48, R30: 50".
- 3
Count rows to the last shaping row
Set Target Goal to 30 and tap + Count after every row.
- 4
Tick each shaping row
Mark each row in the list as done when you finish it.
Shaping Schedule Builder Formula
The Shaping Schedule Builder formula gives the shaping rows, the final stitch count and the total rows covered.
Shaping row k = k × Interval
Final stitches = Starting stitches ± (Repeats × Stitches changed per row)
Rows covered = Repeats × Interval
- Interval
- Rows between shaping rows
- Repeats
- Number of shaping rows
- Stitches changed per row
- 2 when shaping at both ends
Worked example: Start with 40 stitches and increase at each end every 6th row 5 times. Final stitches = 40 + (5 × 2) = 50. Rows covered = 5 × 6 = 30.
Shaping Schedule Builder Conversion Table
The Shaping Schedule Builder conversion table turns the rule "increase 1 stitch at each end every 6th row 5 times" on a 40-stitch sleeve into rows, counts and widths at 16 stitches per 4 inches (10 cm).
| Shaping row | Stitches after row | Sleeve width (in) | Sleeve width (cm) |
|---|---|---|---|
| 0 | 40 | 10 | 25.4 |
| 6 | 42 | 10.5 | 26.7 |
| 12 | 44 | 11 | 27.9 |
| 18 | 46 | 11.5 | 29.2 |
| 24 | 48 | 12 | 30.5 |
| 30 | 50 | 12.5 | 31.8 |
Row 0 is the starting width before any shaping. Each shaping row adds 0.5 inch (1.27 cm) of width.
What is a Shaping Schedule Builder?
A shaping schedule builder is a tool that turns a written shaping rule, such as "increase every 4th row 6 times", into a row-by-row list with the stitch count after each change. The Crochet Stitch Counter Shaping Schedule Builder shows the full plan before you start.
Shaping rules compress many rows into one sentence. Sleeves, darts and raglan lines combine an interval, a number of repeats and a stitch change per row. Writing the plan out shows the final stitch count, the last shaping row and the rows left plain.
The schedule works for increases and decreases, and for rules that mix two intervals such as "every 4th row 3 times, then every 6th row 2 times".
What are the Uses of a Shaping Schedule Builder?
There are 4 main uses of a Shaping Schedule Builder.
Planning sleeves
Cuff-to-underarm increases spread evenly along the sleeve.
Adding waist shaping
Decreases and increases on a schedule give a fitted body.
Resizing patterns
A new interval spreads the same shaping over more or fewer rows.
Checking pattern math
The final count from the schedule matches the pattern's stated number.
