How to Sew Your Own Pajama Pants

How to Sew Your Own Pajama Pants
This instructable shows you how to sew easy-to-make pajama bottoms in any size. I don't know if you have shopped for any pajamas lately but they are crazy expensive. At Land's End, they want $24.50 plus shipping for toddler-sized flannel pajama bottoms. When you see how easy it is to make PJs, the man behind the curtain is revealed and you see what a racket that is. These pants are for my son's "Fall Festival" day at school which banned costumes in favor of a pajama day.

I also make matching pajama bottoms for the family every Christmas because I am crazy and I like everyone to match in the Christmas morning pictures. I don't care if my hair is sticking up or my husband needs a shave but we all must match in the pictures like the Brady Bunch on Tour every Christmas morning. It is not possible to find matching pajamas in the four sizes we need so I buy enough awesomely cheesy Christmas flannel to outfit the whole gang. Then we get plain t-shirts in a complementary color so we can keep on, keep on, keep on dancing through Christmas day.

One small disclaimer:
If you're making kids' pj pants, these are technically supposed to be called lounge pants because they are made from regular woven cotton or flannel and worn by children. There are all kinds of laws addressing the safety of children's sleepwear and anything worn to bed by children is supposed to be snug-fitting in case of fire. That's why all those stretchy cotton PJ sets for kids are tight as an old lady's compression hose. They don't want to get sued if your child gets burnt in a fire. The looser PJ pants are made from fire-retardant material which never feels nice like cotton. So send your children to bed in these pants at your own risk.

To make sure you get the right size, just make sure you have a pair of pants that fit the intended pajama wearer. If your pajama wearer is far away, then find out the right size and borrow some pants from someone who is that size or carry yourself down to the Salvation Army and part with a couple of your increasingly precious dollars for a busted-up pair you can use as a pattern. This is a DIY tutorial and I figure anyone smart enough to sew up some pajama pants is also smart enough to find some in the right size but you never know.

Fabric - woven cotton or flannel or jersey or whatever floats your boat. The exact amount you need will depend on how big the pants are and whether the print is directional or not. If you are an experienced sewer, you know what that means and you can skip the next bit or you can read it and think, "Well, duh." A directional print is one that has a right-side up. Like words or Christmas ornaments or something else that is meant to hang only one way. If you're making adult pants and using a directional fabric that's a standard 44" wide, you will need almost twice as much fabric because you can't save fabric by flipping the pattern around and cutting one leg upside down. If you don't buy extra fabric and move the pattern down along the same fold to cut the second leg, your husband's cheesy Christmas pajamas will be even more cheesy because the aforementioned Christmas ornaments will be hanging down properly on one leg and, in total defiance of gravity and common sense, hanging UP on the other leg. (Sorry, dear.) To use the smallest amount of fabric possible on your "lounge" pants, buy a cute print that looks the same turned any direction.

You'll also need thread to match, pins, paper to make the pattern, a pencil or pen, scissors, a safety pin, and enough elastic to go around the waist of the wearer plus about five inches. What kind of elastic isn't all that important but it should be about 1 / 2 inch wide.

A great source for elastic is your hubby's worn out underwear. The underwear usually croaks way before the top band. Nice wide elastic and it didn't cost a thing! :)

if you use muslin for your pattern you can use it over and over again.

Knocked a pair of these out in an hour and a half. Mmm, flannel jammie bottoms.

Brilliant (and funny) instructions. Thanks a lot!

What great instructions! I just have one quick question: When we place our pattern on the fabric to cut, do we need the1/2" seam allowance on the straight edge that goes along the fold of the fabric, or no? I'm such a nervous sewer and I want to do it right! :-)

What great instructions! I just have one quick question: When you're cutting out the pattern, do we need that 1/2" seam allowance on the outside straight edge that we marked on our pattern, or do we not need that and put that straight edge along the fold w/out the 1/2" seam allowance. I'm such a nervous sewer and I want to do it right! :-)

Thank you -sew- much for this. It's clear, easy to follow, pictures are great, and you're hilarious! I'll be using this for a long time to come.
I'm making a pair for my Dad right now and I wanted to be fancy, so I'm putting some pockets in.
You're great! Thanks again!!!

I don't quiet understand this part of the instructions. I am making pj pants for a 7 year old who takes a size 8 childrens, (atleast thats the size of pants i measured) and i only bought 1 1/2 yards of fabric.
Anyway ,the part i really don't understand is what you mean by "Fold your fabric just enough to accommodate your pattern" and in the picture it shows it folded in half twice.

Oh! Thank you so much! That really cleared things up. Thanks again! :)

Thanks for awesome instructions. I was able to make a toddler a matching pair of pajama bottoms out of a pajama top utilizing the sleeves as legs. I also appliqued a plain Toddler shirt to match the pants. (To find similar matching pajamas for my daughter & 2 granddaughters cost $160 total online.) Though I had to buy an additional pair of women's pajamas in order to make the toddler pants, I used just the top—allowing my other daughter to have the intact PJ pants. By doing it this way, I only spent $80 for all 4 people. I think they will be thrilled on Christmas Eve.

I'm so glad I've found this site! My husband (who's great at crafts) has decided that we should make each other a gift for Christmas - I don't have a creative bone in my body and had no idea what to make.

One thing I can do is sew (I made him a great Austin Powers suit from some old velvet curtains a few years ago), and he can never find PJ bottoms long enough so this idea will be my saving grace.

Thanks Compwalla, you're a star!!

Hi Compwalla,
I was wondering if one could use a knit material for these pants? What changes would need to be made in the sewing technique?
Thanks! Great instructable, by the way.

Thanks so much! Saves us a bunch on christmas gifts this year I'm glad I came across this instructional. Now... All I need is a 6pack to bribe my husband into being a good sport and being my "test subject" for the first pair of pants.
Question: Would there need to be any modifacations done to the pattern to work with a pregnant woman's increasing belly??
Thanks Alot!

I have the material, pair of fitting pants, and paper for pattern all set to go. Just wondering if you've ever tried making the back rise longer than the front, or should I just go with the same for front and back? Thanks!!

Excellent idea - definitely going to try this. And such subtle, old-fashioned fabric too - like the kind Grandma might have worn on Christmas morning XD

This is great!!! Thank you so much for all the good info and you cracked me up! I will make my husband crazy by making him wear matching pants! =)

Thank you! Thank you! Thank you! I plan on making these for Christmas. I am going to put our first initials on a plain t-shirt with the same fabric. You are saving me a crap-ton of money!!!!!

This is an excellent tutorial. Made several pairs and they all turned out well! Thank you!

Thank you!! After reading several pj pant descriptions on-line I came to this one and wow, it doesn't get any better. These directions work! So often I try a store bought pattern and it comes out so badly fitting (usually too tight) that I give up frustrated and sad a nice piece of fabric I was excited about went to waste. I have many of those sitting as scraps in my sewing box. But with your instructions I made a pair of perfectly fitting pj shorts in about 1 hour! I just followed the instructions but traced a pair of pj shorts rather than long pants. Thank you so much for posting. If you have directions for any other sewing projects please share!

Thanks for the tutorial and for the great ideas! I started this morning and few hours later I had perfectly fitting pj bottoms and a matching tunic top! I used an old sheet with a paisley pattern.
thanks again!

I just wanted to say thank you. I saw this a long time ago and it finally came in handy! Your instructions are great. I don't have a lot of experience sewing.....yet but this was SO helpful. Thanks to you my boyfriend has christmas presents no one else will have :)
Dec 10, 2010. 4:27 PMksid4now says:
Thanks again for this, I made it through until the elastic and then realized I don't have any. So much for the gathering your materials first! Great instructions!

Great tutorial! I love sewing without buying patterns. I reposted on my blog about making things (mostly presents right now) at http://maketwincities.blogspot.com/

I really loved reading your how-to, I'm still chuckling over the grandpa pants bit...
But now I have a question!


I have a LOT of sewing experience. But I have never, ever, sewn anything for a man. Now I am trying to make a pair of pj pants for my boyfriend for Christmas and I have no idea how to do the open-crotch thing. He and I are basically the same size, so I was going to trace my own pjs to get the pattern, but then I remembered that he'd probably be more comfortable if I could figure out how to do a front opening. I'm guessing it is similar to jeans, but I don't know about the length from waistband to crotch, or how much I need to overlap the fabric to keep the pants decent when he's sitting down...
Since you've made lots of pj pants, do you think you could give me a few pointers? Thanks!

I've used your ible a couple of times for the last 2 halloweens to make their costume pants. my sons were very impressed with my amazing skills. thanks for making me look awesome!
