These have become one of my absolute favorite baby items! Our little girl spit up a good bit and spit milk out of her mouth or had it running out while eating a good bit more! These burp cloths pack small (like in the diaper bag or a basket full in the family room) but absorb a lot of mess very well.
I simply used second hand receiving blankets and scraps from making other projects with flannel.
First, you cut out two rectangles the size that you want, I used 9"x16". Then just serge around the edges and pull the threads through. If you don't have a serger, sew the right sides together (leaving a space to flip), flip it right side out, press, and sew around the edge again (being sure to close the space left open).
(burp cloths need folded!)
It was a super easy process - which is good, because I ended up needing to make a lot!
I also love that they are cute - when feeding baby is difficult (and little miss has given us many difficult feeding days), the cute changing prints on the cloth at least give a little something special to each feeding.
(there is usually one under her head when she's laying down - not that she's ever been known to spit up or let milk dribble out of her mouth long after a feeding is finished)
