Has anyone done this pattern? I'm new to crocheting and only got through the first row of instruction. Now I'm stuck. The first row is 38 3-dc blocks. Now I'm supposed to "ch 3, dc in first sc, (sc, ch 3, 3 dc) in each ch-3 sp across to turning ch" I get ch 3 and dc in first sc but the 2nd half - sc, ch 3, 3 dc in each ch-3 sp across leaves me stumped. Any ideas???
