I traced the boys hands... I left him to colour them... I cut them out during quiet time (took all of 2 min) Then I had him cut a straight line of paper. I folded it and wrote "this much" On it. On one hand I wrote "I Love You" Then we glued the hands to each end of the straight paper and he had a nice little card that when opened said, I love you this much.
Thank you to the person who pm'd me their pinterest board and I found it there.
