I like sewing pajama pants like this because it eliminates the guess work. No matter how accurate I am with the weight and height of my child, the outfit inevitably ends up being way too big when I use a printed pattern. That’s just the way sewing patterns are (at least for me). I’ve been making pajama pants and pants for Halloween costumes using this method for several years. It is really very simple. This is the exact tutorial that I shared in 2009, I just updated it with newer, brighter photos, of the pajama pants that I made last week.
Does your family have the Christmas pajama tradition too? Our kids (and sometimes mom and dad) always receive pajamas on Christmas Eve. Sometimes homemade, sometimes store bought. They were so thread bare this year that I made some quick pants to wear from now until Christmas and I will be ordering Flannel pajamas sets for Christmas Eve.
To sew pajama pants without the hassle of a pattern, just grab a pair that you already have. I used an old pair of Kaylee’s .
I folded them in half, laying the fold of the pants on the fold of the fabric.
Cut 2 pieces (one for each leg) on the fold, using your old pair as a guide. Make sure to leave at least 1/2″ for seam allowances on the sides. You will need about 3″ on the top for the elastic casing, and an inch or so for the bottom hem, depending on how big you make it.
I like adding a bit of extra space in the crotch area (where the back comes to a point) so that there is plenty of room to bend over and move around without stressing the seam.
Fold them inside out and sew along outer leg edge (from the bottom, to where the crotch begins to curve). Trim close to seams.
Turn one leg right side out and stuff it inside the other leg. Right sides of fabric will be facing each other. Make sure that the long seam that you just sewed on each leg matches the other. Pin in the center to keep it in place.
Sew once more close to the seam line to reinforce since this area will get a lot of wear.
Turn pants right side out. Almost done!
I used 3/4″ elastic. I folded down the waist 1/4″ inch and pressed it. Then I folded it another 1 1/4 inch and sewed the casing all the way around with a 1/4″ seam, also leaving a 2″ gap to insert the elastic into later.
Insert your elastic using a safety pin to help guide it through the waist band. The elastic should be the same size as your child’s waist + 1″.
Sew ends together. Stretch the waist, pulling the elastic back into the opening. And sew the gap closed.
Fold up hem and press, then fold up one more time and press. This one is about 1/2″. Sew around on both legs. Flannel is so easy to work with. You don’t need pins since it pretty much just sticks together.
