This pullover is worked from the top down in one piece, using the granny stitch. Then joining yarn to make a ribbed collar. It’s quick and easy to work up and is great for using up scrap yarn. It can also be made using the granny spike stitch (instructions to adapt included in the PDF)

The pattern comes in sizes 0-3 months to 10 years.
