Crochet Block & Space Grid Pattern (US Terms)
Foundation Chain:
Ch a multiple of 20 + 3 (the +3 is for turning).
Row 1:
Ch 3 (counts as dc), dc in next 2 sts.
Ch 2, dc in next st, ch 2, dc in next st → this covers 12 stitches (block + spaces as shown).
Dc in next 4 sts.
Ch 2, skip 2 sts, dc in next st, ch 2, skip 2 sts, dc in next st → again cover 12 stitches in this way.
Repeat this sequence across. Turn.
Row 2:
Ch 3, dc in each dc and in each ch-space across. Turn.
Row 3:
Dc in first st, ch 2, dc in each of next 12 sts.
Ch 2, skip 2 sts, dc in next st, ch 2, skip 2 sts, dc in each of next 12 sts, ch 2, dc in next st.
Repeat sequence across. Turn.
Rows 4–6:
Repeat Row 3.
Row 7:
Repeat Row 1.
Row 8 onward:
Continue repeating the sequence:
- Row 1 (grid row)
- Row 2 (solid row)
- Row 3 repeated for 3 more rows
- Back to Row 1
This will give the exact grid and block texture like in your chart — large blocks of dc framed with spaced grid lines.
