To sew pajama pants without the hassle of a pattern, just grab a pair that you already have.
- Use a pair of pajama pants that you already have and fold them in half.
- Lay the fold of the pants on the fold of the fabric.
- Pull the crotch area out a bit so that it is pointy.
- 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.
- Note: 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 the 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 the crotch seam of the pajama pants. Begin at the waist, sew along and end at the top again.
- Sew once more close to the seam line to reinforce since this area will get a lot of wear.
- Turn the pajama pants right side out. Almost done!
- I used 3/4″ elastic. The elastic should be the same size as your child’s waist + 1″.
- Fold down the waist 1/4″ inch and press it.
- Fold it another 1 1/4 inch and sew 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 waistband.
- Sew ends together. Stretch the waist, pulling the elastic back into the opening.
- Sew the gap closed.
- Fold up the 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.
