Blue Lap Blanket

So, I would not put these yarns together normally, but my mother bought them and insisted that I try, so this blanket is not consistent at all, but I will admit that it is warm. It is single crochet worked in the round, 2 balls of bernat blanket in blue (obviously from 2 different dye lots) and then 2 skeins of something I don't remember in grey. It was worked in the round in single crochet with 1 row of double crochet in the middle of each of the blue skeins. Then on each of the two sides I worked one skein of the grey to make it a rectangle, also in single crochet.
