This little frgoggie hat was hand crocheted in acrylic yarn. The eyes are crocheted as half balls, stuffed with leftover yarn ends and stitched on. The facial features are embroidered on. Other things that I sometimes add to the froggie hat are bows and long silly tongues. This hat is made without a pattern but any basic beanie cap pattern could be used for the main hat. I have made this froggie hat in all sizes, preemie-adult. Ribbit.
