How the Matching Piece Tracker Works
The Matching Piece Tracker works in 4 steps.
- 1
Record the first piece
Write the first piece's final rows, shaping rows and stitch count in the notes box.
- 2
Set the reference target
Enter the first piece's row count into Target Goal.
- 3
Count the second piece
Tap + Count after each row of the second piece.
- 4
Compare at shaping points
Check the stitch count on each shaping row against the first piece before continuing.
Matching Piece Tracker Formula
The Matching Piece Tracker formula converts a row difference into a length difference.
Row difference = Piece A rows − Piece B rows
Length difference = Row difference × 4 ÷ Row gauge
- Piece A rows
- Rows in the reference piece
- Piece B rows
- Rows in the matching piece
- Row gauge
- Rows per 4 inches (10 cm)
Worked example: Sleeve A has 80 rows and Sleeve B has 77. At 18 rows per 4 inches, the length difference = 3 × 4 ÷ 18 = 0.67 inch (1.7 cm).
Matching Piece Tracker Conversion Table
The Matching Piece Tracker conversion table shows how a row difference between paired pieces turns into a length difference at 2 row gauges.
| Rows different | sc at 18 rows / 4 in (in) | sc (cm) | dc at 8 rows / 4 in (in) | dc (cm) |
|---|---|---|---|---|
| 1 | 0.22 | 0.6 | 0.5 | 1.3 |
| 2 | 0.44 | 1.1 | 1 | 2.5 |
| 3 | 0.67 | 1.7 | 1.5 | 3.8 |
| 4 | 0.89 | 2.3 | 2 | 5.1 |
| 5 | 1.11 | 2.8 | 2.5 | 6.4 |
| 6 | 1.33 | 3.4 | 3 | 7.6 |
| 8 | 1.78 | 4.5 | 4 | 10.2 |
| 10 | 2.22 | 5.6 | 5 | 12.7 |
A difference over 0.5 inch (1.3 cm) shows clearly on sleeves and mittens.
What is a Matching Piece Tracker?
A matching piece tracker is a tracker that compares progress on paired pieces, such as sleeves, mittens, socks or amigurumi ears, so both end with the same counts. The Crochet Stitch Counter Matching Piece Tracker shows the gap between the first and second piece.
Pairs must match. A sleeve 3 rows longer than its partner shows on the finished sweater, and amigurumi ears of different heights tilt the face. Many crocheters finish the first piece, then lose its counts before starting the second.
The tracker keeps the first piece's counts as the reference for the second.
