How to Sew Pajama Pants | Free Pajama Party Pants Pattern

The Pajama Party Pants Pattern is an easy sew that requires very little in the way of supplies. It allows you the choice of knit or woven fabric and 3/4″ elastic. This would be great to sew up at Christmas time for your children or grandchildren. Perhaps your child is having a slumber party for their birthday?!

What a great way to tie in the theme! Or maybe you need to add a few pairs to your child’s wardrobe like I did for mine; whatever the occasion, this pattern will help you meet the need in no time!

Pajama Pants Supplies:

• Peek-A-Boo’s Pajama Party Pants Pattern
• Medium-weight wovens or knits such as: cotton, flannel, interlock, jersey etc.
• 3/4″ elastic for waistband. See chart in pattern for cut length.
• Sewing machine, coordinating thread, needle, pins or clips, safety pin and an iron.

After washing, drying, and ironing my fabric, I cut out my pattern pieces. I chose cotton woven for this pajama party pant tutorial. I thought this would be a good choice as we move into the warmer months here, where we live, as it doesn’t get overly hot. Since I’m sewing this up for my almost one-year-old, I chose to omit the pockets.

If you would like to include pockets for yours, please see the pattern directions for that process. Pockets are pretty simple to add in, and I know some children really love the pocket feature. My middle child always requests pockets for his makes!

Ok, we are ready to get started with our Pajama Party Pants tutorial!

Step One: Leg Seam Construction

You should have two opposites for each front and back leg piece. We will take one front and one back leg and sew those together to create the outside leg seam using a half-inch seam allowance. Clip or pin in place and sew. Repeat for the other front and back leg pieces as shown.

Our outer leg seam allowance is complete.

*Since I used woven fabric, I went back through and sewed a zig-zag stitch along the outside edge to help minimize fraying. Serging or pinking shears are two other options you could apply as well. This step is not necessary if you are sewing with knit fabric.

I also pressed both leg seams for a neater-looking finish.

Step Two: Pressing the Waistband and Hemline

Press the waist over a quarter inch towards the wrong side of the fabric and then fold over one more time so that it measures one inch. Repeat for the other leg piece too.

Repeat the same steps for the bottom hem. Fold over a quarter inch and then one inch and press in place. Repeat for the other leg hem as well.

Step Three: Pants Inseam

Unfold the creases we just made for the waist and hem. This will be important for the next few steps that nothing is folded over at this point.

With right sides together, fold each leg piece onto itself and clip or pin in place. Sew the pants inseam using a half an inch seam allowance. Make sure the creases we created are smooth and not trying to fold back over.

The inseam completed and again, I went back through and finished the edges to prevent fraying. Don’t forget to finish your edges if you are using woven fabric.

Step Four: Hemming

Refold the bottom of each pant leg using the previously pressed creases as your guide. I clipped mine down with a couple of clips just to secure in place, but the creases did their job well.

Topstitch each pant leg in place along the folded edge.

Step Five: Crotch Seam

Take one leg piece and turn it right side out. You should have one pant leg inside out and one pant leg right side out.

Slide one leg inside the other leg so that the right sides are together. Make sure your waistline creases we created are unfolded and the inseams are aligned.

Sew along the rise using a shorter stitch length or by sewing the seam twice to keep the seam strong.

Again, I went back through and did a zig-zag stitch along the edges after completing the seam.

Step Six: Waistband Construction

Refold the waistband crease that we previously made. Topstitch the waistband to the pants along the bottom folded edge, leaving a one-inch gap in the back to thread the elastic through.

Our waistband has been topstitched in place. Now we will thread our elastic through the one-inch opening we left in the back. See the suggested elastic cut chart at the beginning of the pattern instructions for your size. It’s a good idea to get a rough measurement before you cut the elastic to see if the suggested length will work for you.

Once the elastic has been cut to size, we will thread the elastic through with a safety pin and then we will overlap the elastic ends by half an inch and sew them together to secure.

Tuck the elastic inside the waistband. If you would like to add a tag to the back, go ahead and do that now and topstitch the opening of the gap closed.

Our Pajama Party Pants are complete! Time to try them on!

My little guy is becoming quite the wiggle worm as he approaches his first birthday this month.

This is the best we could do for styled photos on this day, but he was happy either way. I’m sure these will get him through the coming months as I added length to his size to accommodate all the growing he’s going to do.

Well, this brings us to the end of our sewing tutorial with another great pattern from Peek-a-Boo Pattern Shop. Now you know how to sew pajama pants. Sometimes I just appreciate a quick sew that gets the job done by providing the clothing items that my children need at the moment. I also love patterns that allow you to switch between knit or woven fabrics for so many reasons.

Who will you sew up a pair of Pajama Party Pants for?
