thanks to this
ikea bag hack from
funk station, greg of
daddytypes was inspired to create a diaper bag complete with changing pad out of a single big blue ikea shopping bag.

you'll need to unpick the seams of the bag first. turn the top portion into a narrow tote bag and sew the two identical leftover pieces together as a changing pad.

if the changing pad is a little too thin for your liking, add a padding layer to it.

diaper bag and changing pad flickr instructions.
