Tools and materials:

  • Fabric with Halloween design (2 yards)
  • Scissors
  • Marking chalk
  • Sewing machine
  • Pins
  • Drawstring (can be a ribbon, cord, or string)
  • Safety pin
  • Buttons
  • Needle and thread
  • Pajama shorts, t-shirt, and collared shirt for the pattern
Tracing pajama shorts to make the pattern

1. Make the shorts pattern

First, fold your fabric in half. Lay your own pair of comfy pajama shorts that you folded in half on the center seam, directly on top of the fabric. 

Adding length to the pajama shorts

Add 1½ inches to the length of the shorts. 

How to make your own pajamas

Trace the outline of the shorts with a ½ inch seam allowance. 

Tracing the back of the pajama shorts

To make the back, continue with the folded fabric. Lay the folded shorts on top as well. 

What measurements are needed to make pajamas?

When you trace, pull out the crotch area to add an additional full inch to accommodate the backside area.

Cutting out the Halloween fabric

Cut out the fabric to match the pattern.

Tracing a t-shirt for the pajama top

2. Make the top pattern

To make the back, fold a t-shirt in half so the sleeves lay directly on top of each other. Lay it on top of the folded fabric and trace the neckline, sides, armhole, and length. We will make the sleeves separately.

To make the front, you will need two pieces for the front and they should mirror each other. Use the folded t-shirt to trace the pattern but add an additional 2 inches from the edge of the fold to where you lay the t-shirt. (See the faint line above).

This is because the front of the pajama shirt will button up and we need more space in the front! Add a ½-inch seam allowance for the back and front pieces. Cut out the fabric.

Making sleeves for the pajama top

3. Make the sleeves

Lay an opened t-shirt sleeve flat on the folded fabric. Trace the sleeve and then cut it out.

Using a collared shirt to make the pattern

4. Make the collar

Use your own collared shirt as a pattern. Lay the collar perfectly flat onto the folded fabric.

Sewing pajama shorts

Sew the center seam for both.

Sewing the front and back piece together

Lay the sewn front and back panels to the right sides are touching. Pin the side seams in place. Sew with a straight stitch.

Sewing the crotch of the pajama shorts

Now pull the crotch pieces together and sew them together on the wrong side.

Now it’s time to get those shorts to fit your waist and be adjustable. Fold over the top about an inch to 1½ inches. Create a tunnel by sewing down at the fabric edge on the wrong side. Leave space to pull the drawstring through.

You may need to use a safety pin to pull the string through. Once it meets, pull it through to be able to tie.

Hemming the pajama shorts

Hem the shorts by folding the fabric over once and sewing it down with a straight stitch.

6. Sew the top

Lay the back of the shirt with the right side facing up. Lay the 2 front panels with the right side facing down. Sew the shoulder lines and the side seams only.

Sewing the collar of the pajama shirt

Sew the collar on the open edge and fold in half. Place to the side.

Making facing with the leftover fabric

Make facing from the leftover fabric. Match the open edge of either front panel with the fabric. Cut the fabric. 

Pinning in place, ready to sew

Pin in place. Sew the facing.

Pinning the facing to the collar

Add the collar and place the facing over it.

Attaching sleeves to the pajama top

Now it’s time for the sleeves. Double fold the flat end to hem. 

Sewing sleeves onto the pajama top

Sew with a straight stitch. Then sew the side seam. Tuck the sleeve right side facing into the wrong side facing shirt. Match the side seams. Pin in place and then sew with a straight stitch.

Adding buttons and buttonholes

8. Add buttons

Lay the shirt so the right side is facing up. It’s time to add the buttons. Line them up. Place a pin to both sides to determine placement. Hand sew the buttons and make buttonholes.
