I use snappied or pinned prefolds. DS is outgrowing his small covers, and I need to buy more in the next size. I was looking at Flip covers. They are on sale, buy 2 get one free, so 27.90 for 3 covers. Econobum covers are 8.95 each. I have one Econobum cover. It works just fine and covers the prefold well. It feels a bit flimsy, but has good reviews. I am curious about the Flips. I like the colors and that they are one size. They are a good price if I buy 3, but I don't want to buy 3 and have them not work over my prefolds. I don't want to buy a whole new diapering system. I already have premium prefolds for when DS outgrows the infant size he is in now.
Have you used Flips over prefolds? How do they work for you? If you have tried Econobum too, do you like one better?
