Thanks to Tiffany for this Frugal Baby Tip!
I made liners for Logan by serging together 4"x10" rectangles of terry & flannel. I put the flannel side next to his butt, so it's nice & soft. I used some cheap "irregular" towels for the terry & bought the flannel for only $3 for one yard, and so for about $6 I was able to make 2 dozen liners.
I use these instead of disposable liners, and they catch most of the poop. Then I just have to dunk the liner instead of the whole diaper!
