Peggy, this is for you:

Block and Offset Shell stitch pattern (US terminology)

Multiple of 11 sts + 4 (add 2 for base chain)

Row 1 (right side) (actually I don’t see why this makes a difference, because the pattern is reversible) Skip 3ch (count as 1 dc), 1 dc into each of next 4 ch, *skip 2 ch, 5 dc into next ch, ch 2, skip 3ch, 1 dc into each of next 5 ch; rep from * to end, turn.

Row 2 Ch 3 (count as 1 dc), skip first st, 1 dc into each of next 4 sts, *skip 2 ch, 5 dc into next dc, ch 2, skip 4 dc, 1 dc into each of next 5 sts; rep from * to end, turn.

Rep Row 2 for as long as required.

There you have it. Very easy to memorise.
