When I stumbled across this great parking garage craft on Spoonful, I got ridiculously excited. Seriously - a craft my guys would love to make, love to play with, and that would use up some of my out-of-control stash of toilet paper rolls. Major score.
The full instructions are on Spoonful, and I won't bore you with the details (not surprisingly their garage also looks way more profesh). It is a pretty simple craft - cover toilet paper rolls with coloured paper, cut one side off a cereal box, draw on parking spots, glue rolls between the two sides of the cereal box, and add ramps. It was a short enough activity that Cam and I could do it while Will was at school, which meant that Cam could actually get to participate in all the making (Will is a little... um... enthusiastic when we all do stuff together). I have to say, he is a pretty fun co-crafter.
