I had purchased a pack of prefold cloth diapers to have on hand for various messes. Whether they were burp cloths or something to have handy when changing a little boy's diaper, they just make great extras to have on hand.
I had some left over fabric from my blankets so I decided to embellish a few with pieces of flannel. In fact, these sewed up so quick I looked for some other left over flannel I had on hand, but I ended up not having enough of either pattern. A quarter of a yard should be plenty to get you one or two burp cloths depending on the size of your diapers.
You can pick up prefolds pretty much anywhere now. Mine came from Target.
You'll want to start by measuring your prefolds. (You can actually start by washing your diapers and flannels, but I felt like living on the edge)
I wanted mine to extend a little past the center padding, but you can decide how wide you want your piece of flannel to go. Just give yourself an extra inch seam allowance on all four sides.
My diapers measured out to 19.5x5 inches. I added 2 inches to this for the 1 inch seam allowance bringing my cut flannel pieces to 21.5x7 inches.
You'll next want to iron your seams.
Not all diapers are made equal so be sure to place your piece on each diaper to make sure your seams will cover the area you want. Otherwise when you pin it it will drive you crazy.
Pin your piece of flannel to the diaper.
Sew using a zigzag stitch as close to the edge as possible. Keep your needle down and turn your diaper at each corner to make the process easier.
It's such an easy way to dress up an otherwise boring cloth diaper!
