Well, Fabric Donkey has taken the idea from rad to FLIPPIN' BRILLIANT.
For serious. She's got a kid about the same age as Kid and Bug, and knows that 3 year olds generally have the same attention span as a gnat, so she came up with this awesome activity booklet using chalk cloth and created a pattern... with TWO sizes!
I did the petite size for Kid, so it's easy to stick in my purse, but I think I'm going to make two of the full sized ones for my cousin's kids for Christmas. They're really great - I bet the big size would be fabulous for car trips. We use the petite size in restaurants and short car trips!
Here's the one I did, inside, backside, and front side...
I couldn't find a cool chalk pen like she has in the pattern - my Joann's was all out - so I just kept the pocket seams wide to accommodate regular chalk. Buy the pattern and you'll see what on earth I'm yapping about :)
(fabric is Chalk Cloth, Kona Lime, Get Together (pigs, squirrels, and bears) and some old jeans. Buttons are antler from the husband's stash.
and pattern is available here for only $5! These would be fabulous gifts, or just something to keep your own kid busy!
