This is a pattern for a smple crochet baby tunic. Worked in double crochet and treble crochet with a little shaping it is suitable for a confident beginner.
Yarn requirements are 2 (3,3) balls of MC and 1 ball of CC (as you can see from the photo, very little of the CC is used, so you may prefer to use a yarn from your stash. Any dk yarn would make a suitable substitute. The front and back are worked flat and then seamed.
