This is a free pattern.

These mittens are knitted in the round with dpn size 3.0 mm. One skein will be more than enough for a pair that fits a 2-4 year old. You’ll need scrap yarn in contrasting color for the heart.
My inspiration for these mittens was this cute little poem:
She’s a little bit of sunshine/ She’s a smile to light your days/ She will steal your heart and keep it/ With her warm endearing ways
She’s your precious little daughter/ With a sweetness from above/ Who will fill your years with laughter/ And your lives with lots of love
