I pre-washed all the flannel to prevent shrinkage after sewing. I then cut 2 pieces of diaper flannel approximately 8" x 20", and 1 piece of the patterned flannel in the same size. I stitched them together (patterned fabric pretty side towards the two layers of diaper fabric). I sewed three sides together, then turned it inside out - showing the pretty patterned flannel. I trimmed the two diaper flannel layers a little, tunred under a 1/4" seam on the patterned fabric. I stitched the seam and then stitched all the way around to finish it nicely. That's it! Hope these instructions are clear.
