i did it. i made a pocket nappy out of a PUL cover. it was easy and it works! i took a cover that i didnt use much as it's a bit tight around the legs when covering a nappy (but just right stuffed as a pocket) and cut some material out of an old pair of trackies and sewed it on to the elastic edges of the cover. i cut the front corners so as not to cover the snaps, and left an opening at top back to stuff and i have a pocket nappy! it's really well fitting and the lining material works like that stray dry suadecloth (its polyester mini cordoroy) so it works. and it looks great (even with the wrong colour cotton showing half way around). I'm so clever. i love my new sewing machine.
