I used this great tutorial to make the quilt tote bag - I just made it bigger and added the castle applique. Easy peasy (for most people, anyway. I actually managed to make a mess of it first, but I stayed calm and grabbed the seam ripper:)
Super Easy Tote Bag- tutorial from Poppyseed Fabrics (http://poppyseedfabrics.blogspot.com/2011/02/super-easy-tote-bag-tutorial.html). This is SUPER easy and SUPER cute--I love it except that it is small!!!! You can't tell from the photo but I'm not sure what you'd do with this, maybe more like a purse than a tote bag. I'm about to make one much bigger to use for school.
