here's the decreasing pattern
there's 6 cables and 7 moss stitch sections. i'll copy the 1st dec row instructions:
Patt 4, work 2tog, *patt 8, work 2tog, patt 6, work 2tog; rep from* to last 14 sts, patt 8, work 2 tog, patt 4. Work 5 rows straight.
the cable/moss stitch pattern is 4 rows. It says "the 4 rows from the patt and are repeated throughout".
I hope that helps.
