I knit these hats following Susan B. Anderson's free pattern, Heart on a String. They knit up so quickly because you hold two strands of yarn together (or you can use a super bulky yarn one-stranded). I made the little red one in about 2 hours! I knit the largest one in Spud and Chloe Outer yarn (super bulky). It feels delicious!
I made the two smallest hats with plans to give them to Kathy, the woman who gave me all her wonderful maternity clothes. She has a 4 year old daughter and a 5 month old daughter. The largest hat was orginally intended for the 4 year old, but it came out too big, so I made another smaller one and am going to keep the largest one for me (secretly I am glad!!).

Maybe I should have posed like the model lol:
I haven't had a chance to give Mom her cowl yet, but once I do, I'll post a pic of her modeling it!
It shrunk quite a bit after just one short hot cycle--I nearly cried when I saw how small it got! We stretched it out though and it got to be the size I was hoping for. :)
