This is the garter stitch one size hat I made with the left over yarn from the blue striped sweater in stocking st. Grandson loved it. Said “hat”!!! That 's as good as Thanks Grandma!
I bought extra buttons in little cars, trains, and planes in reds, blues, greens, and gray to sew onto the cap. The planes are in the solid blue at the very top! And the cars and trains travel around the cap.
