I let Megan pick out any fabric she wanted from my stash... she was dead-set on the dogs as soon as she saw them. I was so afraid her teacher wouldn't be a dog person! Turns out the 3-year-old knew what she was talking about... her teacher has a dog and the 2 of them talk about dogs at school.
For the pictures I filled the bag with 2 boxes of cereal and a bag of popcorn. And there's still a good amount of room in there! But I didn't send it to school empty... there were 2 bags of my (almost) famous caramel-chocolate snack mix.
