This is as promised the “how to” for “summer time” ripple blanket.
To begin, you have to make a chain : multiple of 11 + 4… I suggest, just to try out the pattern, to make as in the graphic here a chain of 37 ! ((3×11) +4 = 37) and when you try out and you’re ready to start you’ll make a much bigger chain as big as you want your blanket to be…
For Christina’s blanket I started with a chain of 114 (that is (10×11) +4 = 114) which is large enough for a six years girl blanket
This is a close-up for the valley 😉 (leaving 2 stitches of the previous row and crochet in the 3d one)
You have only to begin with the correct number of chain (always a multiple of 11 + 4) and follow the graphic chart…
