I installed a basket last weekend, and used it in the car this week. It was great just for holding all sorts of odds and ends, not just food. Previously I'd been using a store-bought organizer which hung on the chair, and this is so much better. 'Fits in the middle of the backseat floor, where no one has their feet (tyke's are off the floor yet).

Book holder for the car or bedroom :) "The pockets were cut to 8x9in. with a felt backing. Make all 4 pockets, then topstitch them onto a 11x30in solid panel of felt (front and back) that was sewn top and sides. Overlap the pockets about 3 inches. Insert a piece of cardboard into the solid panel and then finish the last side. Add straps, and done!"
