I found loads of amazing free printables
I used this site- http://minecraftsfanclub.weebly.com/printables.html for the models
for their boxes I covered them using the very cleaver idea from this website - http://unskinnyboppy.com/2013/11/minecraft-magnets-free-printable/ but used the strips to decorate the box instead.
I also used some printable shrink plastic to make these phone charms using the same printables
These are my cards I made too. All using squares of coloured cardstock.
They both really liked them and couldn't believe I had made them.
