Newborn (birth to 2 months) 20" x 28" before washing, after washing about 19" x 27"

All sizes are approximate. Shrinkage varies.  

Need an even bigger size? This is also available in Swaddle/XLarge size.

How do you use a rectangular newborn flat?   Fold in one end and it becomes a square!   Then use the regular flat folds for square diapers from there, or just pad fold it.

  muslin flat diaper wrapped around a baby

Shown is a size One-Size wrapped around baby with ends tucked in. No pins or fastener.  Of course you can use a fastener but it works OK to wrap and tuck since a wrap style diaper cover put over it helps to hold it together. See more pictures.  There are many ways to use these.  It's not scary!   They wash up so easy and the fabric is just amazing. The rave reviews are real and true. Try a six-pack.  If you don't love them as diapers, you have the best dishcloths ever that will last for years and years.  Size Newborn is the perfect dish drying towel. You can't go wrong owning a pack of flats.

One-Size will work under size small covers or larger, but not size newborn, and will fit until potty learning.

Size One-Size is about same size as our size Small/One-Size Birdseye Flat diaper, but this fabric is thicker so it is too big for newborn babies.

how to use a flat muslin cloth diaper on a  newborn baby  This is a size One-Size on a newborn baby.  Use a cover that is big enough to fit over all that diaper if you skip newborn size Muslin.  It is a lot of diaper for a new baby.   Perhaps just don't use a cover.  There is plently of absorbency, as much as a size medium red edge prefold, so if you wrap baby in a wool swaddle, it can work during the daytime just like that since you change newborn babies pretty much constantly anyhow.   There are so many ways to cloth diaper a new baby.   Flats don't have any elastic or bumpy snaps or anything to disturb their comfort.

Made of organically grown unbleached cotton.   This fabric stays the softest of all of the natural fiber diapers.  

What is it? The words muslin and gauze mean the same thing. These are double weave, not the single weave that the popular swaddle blankets are. "Double weave" means that it is basically two layers of cloth woven together on the same loom at the same time to form one thicker layer. That's an oversimplification of the weaving process, but you end up with one layer of thicker fabric than you do from single weaving, yet it is still a one-layer fabric. Thicker means more absorbent, yet since it is still one layer, it has a nice, soft hand. It washes and dries easily and quickly!

This is another option for economical organic cloth diapering. It is like the made of Organic Birdseye Flat Diapers in size One-Size, or about a half inch bigger, but the sizes do vary due to shrinkage variations. These contain slightly more cotton so they are slightly more absorbent. The muslin (gauze) weave is a different weave, slightly thicker, than the birdseye weave, but they really are very similar. The absorbency is comparable to a size medium red edge prefold, whereas the Birdseye (Small/One-Size) is just bit less absorbent than these; closer to a size small yellow edge prefold or a bit more than a yellow edge small but less than a medium red edge prefold. These double weave muslin (gauze) will win in a side by side absorbency test. The birdseye is thus trimmer. So, that means that this muslin diaper in size One-Size is really too big on a newborn baby since it is bulkier, so that is why we offer size Newborn.   

Since they are unbleached, please wash several times on hot before first use to prep them.  The natural cotton oils present in unbleached cotton must be washed off in those first several hot washes before full absorbency is reached.  Easy to wash, quick to dry. Made in Pakistan.

They work just like the Birdseye Diaper. See pictures. This is a relatively new item and we don't have many pictures of this on a baby yet, but the Birdseye pictures are very relevant since they are so similar. Watch our exclusive GMD How To Fold Flat Diapers Video Tutorial!

compare muslin and birdseye

Both of these Cloth-eez diapers start with the same organic cotton so the softness is very comparable even though they are woven differently.

Cloth-eez Muslin Diaper is an organic cotton double weave gauze diaper. Made in Pakistan.

Please wash several times in hot water before first use. Link to more washing information.


Consider Size Large Birdseye Organic Flats which has equivalent absorbency of the size one-size muslin flat.

Unconventional use of flats!

We have been trying to find ways to reduce food waste in our house and we discovered that lettuce wrapped in damp flour sack towels stays fresh for much longer! I needed a few more and wanted something a little thicker and made of organic cotton. My kids are potty trained now but I remembered GMD having great quality flats. The flats have been working great to keep our produce fresh and they’re a good size. I have only washed once so they aren’t super absorbent yet but I’m sure with more washes they will be as is normal with organic cotton.

Why did I wait so long?

I used prefolds and workhorses for six months before mustering the courage to try these. I feared the folding, but it's actually kind of fun. And they size up by adjusting the fold, so you really could use them 'til potty training. You can't beat the dry time...they dry on the rack faster than Baby's workhorses dry in the machine...and they are the perfect match for the locking head pins I use. The most effective fold I've found is the puts all the absorbency in the front and keeps the bum slim. They can't beat the absorbency of the workhorses, and they are a bit much to expect daycare to handle, so they are only about 1/3 of my stash. But for days I know I can change him every two hours, they are the best. Photos of the airplane fold as it works for us are attached. (One size)

I wanted to leave a review because you don’t see many reviews related to older babes and I was skeptical. My little guy is 19 months old and I was worried about him soaking through these, or them not being big enough. He can wear a one-size for two hours, no problem! I absolutely love these. Definitely my favorite diaper! Wishing I had bought all GMD flats and no prefolds from other brands. These are amazing!
