Knitting this as a slouchy hat for my 3yo. I need a hat which has a tight fit to keep the hat in place but is slouchy enough at the top so she can wear a ponytail underneath.

modifications:
co 88 sts with needle size 4.0 mm (7 sts for heart + 1 sts in between);
5 rows stockinette st
7 rows * k,1p1 *
2 rows stockinette st
7 rows of heart-shape
switched to needle size 4.5 after 3.5 inches from buttom

worked increases and decreases loosely according to Felicity pattern
