A simple (in principle) pattern: Chain a multiple of five plus one to desired length (or width). SC in next loop (chain 2, dc in second loop, ch 3 sc in second loop) to end, Ch 3 (counting as a dc), chain 2, sc in first dc, ch 2 dc in first sc) to end (end on a dc) . chain 1, (sc in dc, chain 3, dc in sc,) to end (ending with sc). Repeat the two rows to the length or with desired, Bind off.
In practice, things get a little confused at some places so it looks more random than the orderly instructions suggest. Still, it is light and airy for a summer wrap.
