Kindness T- shirts

This year we are introducing something new.We have been designing T-shirts in our whanau groups also known as house colour groups.I designed my T-shirt with my friend Phoebe as she is in the same  group as me.In our whanau groups we will pick our favourite one,the winning one will be taken to vote on someday the one with the most votes will be taken to get printed.We are designing these T-shirts for our value assembly we have every three weeks.The way you can get these is by showing kindness if someone is being kind in the playground the duty teacher may see this and give them a kindness slit.With the slit you will take to to the office were their is a jar that says #Kindness.In the values assembly the principal will draw out a name from the jar and you may win the T-shirt.
Do you do anything like this at your school?
This is my design
