Lounge in Style: How to Sew Pajama Pants
Pajama pants are a fun, quick sewing project. This tutorial will show you how to whip up a pair of pajama pants from your own pattern. (Don’t worry, it’s super easy!) You can use this tutorial to make pajama pants for the whole family (Matching pairs, perhaps?). Use lightweight fabrics, and they’ll be perfect summer PJs!

What you’ll need:
- Pattern paper (I used a roll of white bulletin board paper; exam table paper or butcher paper also work well)
- A pair of lounge pants that fit well (You’ll be able to make minor fit adjustments, but it’s best to start with something pretty close)
- Woven fabric, such as cotton or flannel; the amount will depend on the size pants you are making (This is also a great project to upcycle vintage bedsheets, which is what I used)
- ½” wide elastic
- Thread to match
Here’s how to sew pajama pants:
To make your pattern, fold your existing pants in half and pull the crotch all the way out. Flatten them out as much as possible and lay them on top of your pattern paper. Trace around the pants, making sure to trace the waist as stretched out as possible if it has elastic or drawstring. If you need to make minor fit adjustments, such as raising or lowering the rise of the pants, or making the legs slimmer or looser, do that now.
Add a seam allowance by tracing a second line 1/2” outside the first line. For the waist and hem, increase the seam allowance to 2”. Cut the pattern out.
With your fabric folded in half, place the long, straight edge of the pattern right up against the fold. Cut and repeat for the other leg. If you do not have enough fabric width to cut on the fold, you can make each leg two pieces. Just be sure to add an additional 1/2″ on the outside leg, and sew that seam before moving on to the next step.
With the right sides together, sew the inside seams of the legs, from ankle to crotch, using a 3/8” seam allowance. Press the seam open and finish the raw edges.
Turn one leg right side out and slip it inside the other leg, matching up the crotch and side seams. Sew along the crotch using a 3/8″ seam allowance. Turn the pants inside out.
To make the elastic casing, fold down the top edge of the waist 1/2” and press. Fold down 1” and press again. Use pins to mark an opening about 3” long to insert the elastic. Sew around the waist, making sure not to sew the opening closed.
Use a safety pin to thread the elastic through the casing. Sew the ends of the elastic together, then sew the opening of the casing closed.
Hem to the desired length.
Take a nap in your new pajama pants!
