Some Background
Prefold diapers can be an extremely cost effective way to diaper your child from birth to potty training. If you just get the basic supplies, and can resist all the cute cloth diapering accessories better than I can, you can probably achieve that goal for under $250.
What makes a cloth diaper a prefold? Prefolds have mutliple layers of cotton throughout the diaper but more layers in the center. A diaper that has the same number of layers throughout is said to be a "flat" diaper. We chose to use prefolds because they looked more absorbant and seemed to be more popular than flats. The following picture highlights the area of extra absorbency.

Prefold diapers tend to come from either China or India. In our house we have only used the Chinese prefold diapers. What's the difference? Chinese diapers are said to be very durable while Indan diapers tend to be softer but less capable of handling a lot of wear and tear. I don't think the Chinese prefold diapers are rough at all but I don't have an Indian prefold for comparison. I do know that P has never had a problem with the diapers and she seems to be happy with how they feel against her skin.
We own 18 newborn sized and 24 premium sized Chinese prefold diapers. We only bought 18 newborn diapers because we were unsure we would stick with cloth diapering and we supplemented with disposables for the first month of P's life. The newborn sized diapers have a green stitching while the premium sized diapers have a blue stitching. All of our diapers are bleached white but you can also by unbleached fabrics. My wife and I didn't really put any thought into buying bleached over non-bleached fabrics, we just purchased what was in stock. All of our prefolds were purchased online from Cotton Babies.**
Here is a side-by-side picture of the premium and newborn sized diapers.
After 6 months of use and laundering the newborn diapers are currently 10" wide x 12" long. After 3 months of use and laundering the premium sized diapers are 12" wide x 17" long. My measurements are a more accurate measure of diaper size than the new and unwashed sizes often listed on retailer Web sites. Prefolds will shrink some over time.
Notice that the diapers in the picture have a texture to them? When you buy your prefolds they will be smooth and a bit stiff. Over time, as you wash the diapers, they will get much softer and take on the fluffy look of the diapers in the picture.
The Basics of Using Prefolds
Here's a quick overview of how to use prefolds. I'll expand on each step in more detail in the 2nd post in this mini-series on prefolds.
Before you use your prefold diapers you need to run them through 6 to 8 full wash and dry cycles to break them in. Unbleached fabrics may require more washes but that should be noted by the diaper retailer or manufacturer. Prewashing your diapers softens them up and gets the fabric into a state of increased absorbency.
Using cloth diapers is straightforward. You apply the diaper using one of several folding techniques. Since a picture is worth a thousand words, here are a few YouTube videos of popular diaper folds.**
My wife and I use all three folds but we primarily use the bikini twist because it fits P the best. The fold you choose is based on a number of factors that include the size of your child in relationship to the diaper, the activities the child will be performing in the diaper, and which fold fits your child's body type.
Once the diaper is folded and around the child you need to secure it using either diaper pins or a Snappi. I have NO idea how to use diaper pins as we only use Snappies. The Snappi is an awesome little invention and I can't recommend them enough. Here's what a Snappi looks like.
Since prefold diapers are cotton they require a cover to keep the fluids from absorbing all the way through the cotton fabric and onto you and your child's clothes. Diaper covers go over the cloth diapers to build a seal between the soon-to-be wet fabric and the rest of the world. We have tried several brands of diaper covers but have settled on using the Thirsties Duo Wraps for P. Our stash currently includes 3 size 1 Duo Wrap covers and 3 size 2 Duo Wrap covers. The type of diaper cover you choose is dependent on the size and shape of your child. I'll talk more about diaper covers in part 3 of this series.
Once the diaper cover is on you are all done! It seems like a lot of work but it isn't that bad once you get the hang of it.
When the diaper is soiled you just unwrap everything in the same order that you put it on. You don't need to wash the diaper covers after every diaper change unless they are soiled. If the diaper cover is just wet you can clean the inside with a wipe and lay them out to dry so they are ready for the next diaper change.
Some Additional Points on Changes and Washing
We don't leave P in a prefold diaper for more than 2 hours if we can help it. The fluids are absorbed by the prefold diaper and will eventually spread to make the entire diaper wet. This can get really uncomfortable for the baby and you may risk giving your child a diaper rash in a very odd spot.
We try to launder our cloth diapers every other day but we never go longer than 3 days between loads. Once you smell the diaper pail you'll understand why!! Diaper covers get washed with regular baby laundry, not cloth diapers (usually), and only when they get soiled by solids or begin to smell. We probably wash ours once a week.
"Wrapping" It Up
This is just a basic overview of the process for using prefold diapers. Hopefully this gives you an idea of what is involved. In part 2 of this series I will talk in more detail about using and caring for your prefold diapers. I will also focus on adapting your folding technique and the fit of your diapers as your child grows.
**Please note that just because I list a retailer it doesn't mean that I am endorsing them. I am also not getting paid for mentioning any retailer in my articles. Over time you will notice that my wife and I have bought our cloth diapering supplies at a number of retailers.
