I showed you this pinafore during kcwc and put together a tutorial with free pattern pieces for you! Yeah!
+pattern piece download (size baby**)
**Pinafore dresses can work also as tops when the baby gets taller. This pattern will likely fit a baby from size 3/6 months to 1 year. Vague but true!
Cut out pieces:
You should end up with:
+4 back pieces
+1 inset of ruffle fabric
+one front lining
Topstitch around the inset with thread that matches your knit.
Sew the backs together also, leaving the side seams open. Clip the corners and turn both backs and the front piece.
Thanks to Ruffle Fabric for the gorgeous ruffles!
