Make pajama pants without a pattern

1. Trace the pajama pants

To begin, trace a pair of pajama pants to make a pattern, following the instructions in the video from 1:20-4:31.

2. Cut out the fabric

Fold your fabric so you have two layers. Place the front and back pattern pieces on the fabric so their straight edges are together and overlapping on the seam allowance.

Trace around both pattern pieces with a fabric pen, as if they were one large piece. Then cut. Because the fabric is folded, you will be left with two mirrored pieces of fabric.

3. Measure and cut the elastic

Measure the waistline of the pants, multiply that number by two and subtract one. This will be the length of your waistband. Cut a piece of fabric of that length, with a width of 5 inches.

Lay the two main pieces together, right sides facing. Then, pin and sew the crotch seams.

13. Fold and pin the waistband

Fold the waistband inwards so the edge overlaps the waistband seam, and pin the waistband in place. 

Stitching in the ditch

14. Sew the waistband

Sew the waistband down by stitching in the ditch (meaning, stitching over the already existing waistband seam so your stitches are hidden).

Do not sew all the way around. Make sure to leave a two-inch gap in the stitching, so you will have a place to insert elastic into the waistband. 

Inserting the elastic into the waistband

15. Insert the elastic

Before inserting the elastic, check your seam and make sure all the parts of the waistband, other than the gap you left for the elastic, have been sewn down securely.

Then, attach a safety pin to one end of the elastic band, and insert it into the gap. Use the safety pin to guide the elastic all the way around the waistband and back out through the gap. 

Sewing the ends of the elastic together

16. Sew the elastic

Sew the ends of the elastic together with a zigzag stitch or straight stitch, then sew closed the gap in the stitching. 

Securing the elastic in the waistband

17. Secure

Sew a few stitches in a few areas around the waistband to hold the elastic in place and prevent it from twisting. 

Trimming the bottom edges ready to serge

18. Trim and serge

Trim the bottom edges of the pants so they are straight and neat. Then serge.

19. Fold, press, and sew

    Awesome! Thanks sew much!

    Couldn’t you just add the waist band height measurement to the top of pj’s and make a casing, then insert elastic. Seems that would be much easier.

    Just a thought.
