Are you ready to sew some adorable PJ pants for your whole family? This step-by-step tutorial shows you how to make easy-to-sew pajama pants in any size.

One of our very favorite Christmas traditions is staying in our pajamas all day on Christmas Day–even right through Christmas dinner. While we don’t usually get new ones every year, it has been a few years since our last set, so I decided that this year, in the spirit of our handmade holiday, I would make matching pajama pants for everyone.

I have explained in previous sewing posts that I am really not a very technical sewer. My seams aren’t always perfectly lined up and I never bother pre-washing my fabric, and I finish my inside edges with a pinking shears rather than a serger. I usually shoot for function rather than perfection, and time-wise, that approach pays off. Each pair only took about an hour to make. If you are really nit-picky or have advanced sewing skills then this tutorial will probably make you crazy. Consider yourself warned! 🙂

Here is what you will need:

main fabric (about 1 yard  for kids’ pants or 2 1/2 yards each for adult pants)
contrasting fabric for cuffs (1/4 yard is plenty)
thread
elastic
pinking shears & scissors
sewing machine
pins & safety pin
pants or leggings to use as a pattern
 

Create the pajama pant pattern using an existing pair of pants.

 Lay pants or leggings down on fabric to see how much fabric you will need. For the kids’ pants (shown) cut the fabric as shown, leaving a couple inches at the top and bottom. For the adult pants you will need TWICE the length of the pants.

Fold the fabric before cutting the legs of the pants.

For the kids pants, fold the fabric as shown, then fold once more so that it is in 4 layers. You will probably not be able to do this for the adult pants unless your fabric is very wide or your pants are very skinny, but for the kids pants it saves a lot of fabric. For the adult pants, fold your fabric lengthwise so that you have 4 layers as well.

Cut the fabric using the pants as your guide. Be sure to leave inches of fabric on either side.

Using your pants as a guide, cut fabric in shape of pants, being sure to leave several inches of extra fabric at the top, and widening the legs to make nice straight leg pajamas.

Cut bright rectangles out of contrasting fabric to create cuffs for your easy-to-sew pajama pants.

To make the contrasting cuffs, cut 4 rectangles of the contrasting fabric that are approximately 4-6 inches wide and as long as the bottom of the pajama pant leg.

Line up the bottom edge of the cuff and stitch together as shown using your sewing machine.

Next place one cuff on bottom of one pant leg with right sides together, lining up bottom edges. Stitch together as shown.

Fold the fabric over and stitch the cuff in place using your sewing machine.

Fold contrasting fabric down, then stitch in place; repeat these 2 steps for all 4 pant legs.

Sew the cuffs in a straight line along the bottom of the pant leg.

When you are done they should look like the picture above.

Pin the pants and stitch them together.

Next, pin 2 of the pieces with right sides together on the curved section as shown, from the top of waist to the crotch. Stitch together and remove pins. Repeat for second set of pieces.

Line up the cuffs and pin the two sides together, right side facing inward.

Open up pieces as shown and pin together with right sides facing in, lining up cuffs as well as you can.

Use your sewing machine to stitch the easy-to-sew pajama pants together.

Once pinned together, stitch the inside seam, starting at the bottom of one leg and curving around the crotch, then finishing at the bottom of the other leg. You can reinforce the crotch with extra stitches, if desired. Next, stitch the outside seam on either side.

Once the pants are ready, turn them right side out and stitch the inseam.

When you turn it right-side-out, it should now look like pants!

Fold the cuff over and pin to the leg of your pajama pants.

Fold the cuff over into the inside, then pin in place. I placed the pins on the outside so that I could see them while I sewed.

Stitch down the cuff of your pajama pant leg using your sewing machine.

Stitch cuff in place by following existing stitch line. You could use a matching thread to your fabric so it doesn’t show; I just use white for everything because it is cheaper and easier!

Pin along the top of the waistband of your pajama pants after folding it over.

Once your cuffs are done, fold the top of waist over just enough to finish the raw edges, then pin and stitch in place.

Leave a gap in the waistband of your pajama pants--this is so you can thread through the elastic.

Fold waist again, this time about 1 1/2″, and pin in place. Mark pins at the stop and start line, as you will need to leave an opening for the elastic. Stitch closed, stitching along the bottom fold to leave room for the elastic.

Use a big safety pin on the end of the elastic--this makes it easier to thread the elastic through the waist band of your pajama pants.

Cut elastic to proper length, leaving a few inches allowance, then attach to a safety pin and guide elastic through waistband. Stitch 2 elastic ends together and then fix waist so that it is evenly gathered all around. Voila! You’re done!

Once you've stitched the ends of the elastic together, your easy-to-sew pajama pants are ready to wear!

I couldn’t have the girls model them since they are a surprise for Christmas Eve, but I did try mine on and take a picture in the mirror. I purposely made mine extra big & long to be extra comfy, and I can’t WAIT to wear them!
