This ensemble is sized to fit little ones 12-36 months. All three pieces to the ensemble are seamless, so not only are there no irritating seams on tender skin, there is none of that time-consuming sewing of pieces together!! In addition, there are no choking hazards to be concerned with; the jumper slips easily over the little girl's head and is very comfortable around the neckline and armholes. This is a great project for a beginning knitter with a little experience and who is up for a challenge. The yarn I use for this ensemble is Caron Simply Soft. There are amazing colors available and it is super soft and easy to work with, but I'm sure some of the super deals that Craftsy offers will work wonderful as well!
