Over the years I’ve crocheted many a blue and green ripple afghan:
2014 #33 – Coastal Chaos
2011 #10 – Inspired by a Beach Tote
2011 #5 – Blue and Green Scrappy.
with randomly placed one and two-row stripes
made from many, many blue and green scraps, plus Caron Wintuk ‘Cornflower’ from yarn fairy Sandi of MD and three partial skeins of white, including Red Heart’s sparkling White.
