Counting Stitches

Ok. So I'm making this blanket for my nephew. I'm not following a pattern is simple singles, half double, doubles , triples and popcorn stitches. But I didn't count my stitches so my blanket is about 2 inches wider in the middle then at the bottom and top. I tried to make it make sense by decreasing stitches once I noticed that was getting too wide.

Lesson Learned: Count your stitches!
