This is Bella.

She is a 7 year old girl who just marked 2 years since she officially went into remission from Acute Lymphoblastic Leukemia! To celebrate this year, we wanted to do something a little different and do a hat and scarf fundraiser and donate to Ellie’s Hats which helps raise awareness for childhood cancer by donating the hats to infants, children and teens who are undergoing chemotherapy.” 

Here is a link to the Facebook event they set up to collect hats. They have collected about 250 hats.https://www.facebook.com/events/669238366527910/?ref=br_tf
