Cloth diaper inserts that you make yourself and they say they were made for less than a dollar each!! That is SO much cheaper. I may have to try this one out sooner rather than later. (See if they actually work as well as the ones you buy.)
DIY cloth diapers- very quick and easy pattern. One tip would be to add all the snaps but the 4 along the edge, wait till after you serge to do them. I made one today having the snaps before serging and my serger foot would have none of it, so I have a weird looking (usable, but very weird looking) diaper. All in all very easy to sew up. Would be a nice way to create a quick stash.
