I made this little diaper/wipe carrier before Joe's surgery. I used this free pattern. It was very easy and sewed up quickly. Instead of using velcro, I used a button and ribbon closure. I'm not much into velcro.
I think if I make this again, I would make it a little wider. The travel wipe container that I use fits a little snug in there. (And one doesn't fit at all.) And wipes are important when you have two in diapers. Especially one being a small infant who is breastfed.
