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 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.

Yes! Oeko-tex Certified!

This is so soft and durable. I love how these flats and the prefolds are oeko-tex certified! That is a huge plus!! So far these have held up well after many washes! There are many uses for this flat, it's so functional! What I love most about it is the dry time, it's quite fast!

Muslin Flats

I was SUPER intimidated by flats, but I knew they absorbed more than most of the inserts I had for my pocket diapers, so I decided to give them a try with these and a Thirsties Duo Wrap cover. I’m in LOVE! These have converted me! After some practice, I’ve gotten better at folding them, and since I started with the flats and covers, I haven’t had a single blowout. I am the happiest mama ever with these diapers. They are trim and super absorbent.

Muslin Flats the Best

These are absolutely my favorite flat diapers. They are my most absorbent cotton diapers. I soak in Oxyclean and never have stains, which cannot be said for my overpriced stretchy bamboo/hemp flats, which stain terribly. These are cushy and get softer with every wash! Buy some, you will not regret these! If I could do over most of my stash would be these muslin flats.

Good for value

Pros: If you are looking for something affordable and gets the job done then this is it. I liked that it was easy to wash and dry, which minimizes ammonium build up. I like these better than prefolds for that reason. Also great for diapering new borns because they go through so many diapers in one day. Good to have a cheap option to bulk up on. Cons: they feel rough. I really disliked the feel of this material. I think the Birdseye feel better than muslin. However both feel rough but I like Birdseye texture more. Organic is nice but wish they were more comfortable. Recently switched to using stretchy flats and love them. Feels so soft and the stretch gives baby more comfort. Maybe green mountain diapers should carry stretchy flats as well?
