The Neat Ripple pattern is one of my absolute favourites for blanket making and over the years that I've been crocheting I've made several. Picture above from left to right :: Summer ripple :: Interlocking Colour ripple :: Coast Ripple.
pattern for this can be found at Haken en Meer (just translate it from the Dutch). It’s basically AWESOME. Looks like a granny stitch but with a small stitch in between. Loving it so much that it’s going on my to-do-sooner-rather-than-later list.
