The pattern is advanced-beginner to intermediate level. You will need to know how to work stockinette, ribbing and garter stitch, increase (m1), decrease (k2tog, ssk, and s2kp), yarn over, cast-on stitches at the end of a row, pick up stitches, sew seams, and work short rows made with decreases. There are many fun techniques in this pattern, so it could be a good chance to learn or practice new skills.
