I found the spiral pattern in one of my stitch dictionaries. I bought 8 skeins of Elsebeth Lavold Hempathy hemp/cotton/modal blend DK-weight yarn, 4 in teal, 4 in royal blue. Hemp is a breathable fiber that softens more with use. I have two half-skeins of each color left. The yarn label didn't have a crochet gauge listed, so I guessed and ended up using an E hook. The yarn softened nicely after washing and blocked dry overnight. The hardest part was blocking the blanket out into the spiral, since the points tended to be very obvious. I think it was a great choice for a hot weather baby blanket. I'm very happy with the blanket! :-)
