OK then LOL. I was going to suggest that you just make a square bag slightly bigger than the books/paper you were going to buy - just a simple one where you get the fabric, fold it, then cut out the size along 3 sides (leaving the fold) then get some PVC plastic from spotlight and cut 2 of these the same size as the unfolded fabric and then sandwich the fabric inside the PVC and then hem the two edges of the opening, then fold in half and sew up each side. You could also add to the fabric before you sew it, fabric letters to spell their names and then get some iron on backing and iron them onto the fabric. To make handles, get some of the fabric and make another 'sandwich' with the PVC and then sew them onto the bag. The PVC means that it can be wiped out if you get a leaky texta/paints and it also wont stain the fabric.
