The jumper is worked from the bottom up. The sleeves are worked first, then they are left on the spare yarn and when the body is done all 3 pieces are joined together.

Testers marked this pattern as easy/intermediate (mostly due to cable stitch). Pattern has step by step pictures on how to make cable stitch without cable needle.
