Bell Flow Team Take Part in Christmas Jumper Day!

For the third year in a row, we have dug out our favourite xmas knits and gladly taken part in Save the Children's annual Christmas Jumper Day!

The money raised from the event helps saves children's lives around the world. Donating just £2 could potentially bring essentials like health care, education, protection and food to children who are missing out on the most basic support. Information on the organization can be found here.

We would like to take this opportunity to wish you a fun and festive Christmas and a happy new year!
