Linda they are super easy and very quick to do. My mother in law was telling my sis in law about them, and sis in law suggested I make some for baby wipe packs... so, being I have no babies, thus no wipes, and no idea the size of the package, mother in law is going to pick up a pack for me to use as a reference.
When I get it done I will post a pic... might be a few days as I am now on the search for a cute baby fabric for the outside hehe.
