Crochet Frog-Back Planner Formula
The Crochet Frog-Back Planner formula counts the rows from the current row back to and including the mistake row.
Rows to frog = Current row − Mistake row + 1
Stitches to frog = Rows to frog × Stitches per row
Restart row = Mistake row
- Current row
- The row on the hook
- Mistake row
- The row containing the error
Worked example: Current row 45, mistake on Row 38, 60 stitches per row. Rows to frog = 45 − 38 + 1 = 8, and stitches to frog = 8 × 60 = 480. You restart on Row 38.
Crochet Frog-Back Planner Conversion Table
The Crochet Frog-Back Planner conversion table shows stitches unraveled and approximate yarn reclaimed for 60-stitch rows of worsted double crochet, at about 1.3 yards (1.2 m) per 10 stitches.
| Rows to frog | Stitches unraveled | Yarn reclaimed (yd) | Yarn reclaimed (m) |
|---|---|---|---|
| 1 | 60 | 7.8 | 7.1 |
| 2 | 120 | 15.6 | 14.3 |
| 4 | 240 | 31.2 | 28.5 |
| 6 | 360 | 46.8 | 42.8 |
| 8 | 480 | 62.4 | 57.1 |
| 10 | 600 | 78 | 71.3 |
| 15 | 900 | 117 | 107 |
| 20 | 1200 | 156 | 142.6 |
Yarn per stitch varies with stitch height and tension. Weigh frogged yarn for an exact figure.
What is a Crochet Frog-Back Planner?
A crochet frog-back planner is a calculator that records your last correct checkpoint and works out how many rows or rounds to rip out to reach a mistake. The Crochet Stitch Counter Crochet Frog-Back Planner shows the cost of frogging before you pull the yarn.
Frogging means unraveling crochet, named for the sound of "rip it, rip it". A mistake on Row 38 found on Row 45 means ripping 8 rows: Rows 45 back through 38. Knowing the number lets you decide between frogging and a local fix.
The planner gives the rows to undo and the stitches that come out.
