Thanks to Julie for this Frugal Baby Tip!
I made some little sleeves kind of like a mini pillow case out of Alova Suedecloth for my flatfolds that I can stuff with whatever combo I need. I bought it at Wal-Mart for $2.97 a yard and I just folded my diapers in 3rds and laid the diaper on top for the pattern and added 1/2" around for seam allowance and I think I whipped up 5 in about 15 minutes.
I really love them because not only do they wick away the pee, but I stuff them and have them ready for diaper changes. I have some stuffed with premium diapers along with a micro fiber rags I picked in the automotive dept that are super absorbant folded in 3rds also. I also use the prorap cover and never had a problem with leaks.
Here's the same idea for the pockets only with fleece...
It's sortof like a cheap version of a pocket diaper!
