Ripple stitch

[Curious]

I am working on a lap blanket with ripple crochet stitch, which I learned on YouTube. 

Have been doing seven double crochets, then chain two, then seven double crochets,  skipping two going into the third stitch.  At the end of the row  I add an extra double crochet where I have put the seventh stitch. Chain three and tern  imy work. The problem is all of the holes do not align perfectly and I don’t know why as I count very carefully. Being new to crocheting I’m stumped.
