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 organically grown 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.

Muslin flats over any other diaper

These are my absolute favorite flats to use. I wish I had started with these from the get go. I initially started with osocozy bamboo cotton flats and they were great until they shrank. Funny story, I read a lot of reviews on Amazon and I kept reading about green mountain diapers in the comments. I finally decided to search gmd and ordered some Birdseye flats and prefolds. After some time I decided to finally try the Muslin, although I had some reservations about then because when you think of Muslin you think light and airy and how is it going to absorb any pee. Well, this muslin is a double weave and let me tell you, it makes all the difference. (Side note: don’t buy the Muslin at Nickis diapers thinking it’s comparable, it’s not! Single weave, though their is no mention of it on the site.) I see a lot of comments saying they are more bulky than Birdseye but it also means that they absorb more. If a trim diaper is more important to you, then I’d suggest using Birdseye for daytime when your able to change baby more frequently. Muslin is what you want for naps and nighttime. It’s takes a lot more pee to make these feel soaked. I used the origami fold because it’s probably the only fold where there is really long wings to fit around my big wide baby. Kite fold works too! These also work great just padfolded. Lastly, these are beautiful! I love folding these straight out of the dryer and when you’re done diapering , you’ll have some multipurpose cloth. Go for it! Buy some flats! They are truly customizable for your baby

Muslin flats

These seem to hold more than the birdseye and we like to use them at night. Sometimes with a doubler. Very soft and thicker than the birdseye.

Very good quality

These are just what I’ve been looking for. I used cloth diapers a generation ago, and was worried about finding good quality for my daughter’s baby. They washed up beautifully and are thick and absorbent. I’m sure they’ll last through this generation.

Natural Fibers Are Soothing Fibers

My foster baby came to us with many sensory and skin issues. The combination of using the cozy snugglewool and these organic cotton muslin flats have done wonders for him. He has beautiful clear skin, never had a rash since we brought him home, and never has sweat lines or red marks. He never cried even when soiled or wet, 2 drops in a disposable has him screaming. He is one comfy baby now.

Great Diapers

We're first time parents on a budget trying to reduce our environmental impact in every possible way. We decided to CD for that reason, and because we live in an apartment AND I wasn't about to deal with stinky diapers (my MIL CDd her babies and I know how bad they can smell), I chose flats. I bought a dozen newborn size and a dozen one size flats. I kind of wish I'd bought a dozen more, but I have just enough for now. My MIL graciously offered to prep these for me (I have a coin laundry) and it took her 8 washes to get them ready. They were nice and absorbent then, but I'm sure they'll keep getting better with a few more washes. I like the NB size but I find the OS flats perfectly useable for my little newborn baby. My husband especially likes to origami fold the OS flats and we like that it's got such a high rise in the back. That said, I like to kite fold the NB flats and like the resulting absorbency. I'm not sure if we just have a very heavy wetter, but I do often lay another cotton flat (super cheap ones we received as gifts - they could never be used on their own but they work okay as doublers) inside to get enough absorbency for the diaper to not be totally sopping wet within 2hrs. If the muslin gets more absorbent as it continues to be washed, this may not always be necessary. I'm super glad I went with these flats. They also look so cute all folded up on the baby!
