The suspect has been identified...

Crime? Walking on the baby blankets.....with feet that should have obviously been wiped before coming inside! Whoops :) Almost everytime we lay a blanket down for Brynn to play on Magnus will sneak over so he can share in the blanket or if we leave it on the floor after play time we'll find him laying on it even though he has the rest of the rug or his chair to choose from!

In case you need a closer look..

This behavior started early when I was still pregnant as he liked to lay on my fabric when I was sewing things for Brynn's room!
