I was in love with this tutorial that I saw a LONG time ago and finally gave it a go. These aren't the best pictures, but I can't fit the baby bjorn carrier over my stomach right now, so will have to get pictures AFTER I have the baby!
I bought the material for the covers when I was in Oregon. Figured if I have a puker, these are easy to take on/off and wash! This will hook to the piece that goes around my shoulders - I just don't have it out yet.
It was VERY easy to sew up. Not nearly as easy to put the carrier into the cover, but it fits!
