How to Make a DIY Witch Costume

Supplies Needed

  • Two 31x20-inch pieces of linen fabric (amount will vary by size of the child)
  • 20x20-inch piece of contrasting fabric
  • Sewing needle and thread
  • 1 yard string
  • ¾ yard of black felt
  • Black headband

Step 1: Cut the Dress

Enlarge and trace the pocket pattern onto paper and cut out. Cut two pockets from the contrasting fabric for this witch Halloween costume. Then sew the pockets onto one piece of linen fabric (for the dress), leaving edges raw.

Step 2: Sew the Dress

With right sides facing, sew linen dress pieces together down the sides. Starting at the top, stitch for 4 inches, then skip 5 inches unsewn for armholes. Sew the remainders of sides together.

Beginner's tip: "Right sides" refers to the side of the fabric you'll want to see on the outside of the garment when you are finished. What becomes the inside is called the "wrong sides."

Step 3: Add the Hem

Fold the top of the dress over 1 inch to the wrong side of the fabric (meaning you should now see 1 inch of the right side of the fabric). Sew along the fold (what we will refer to as casing), close to the raw edge. Leave a 2-inch unstitched opening. Turn dress right side out. Lace string through the casing. This will help size the dress to fit.

Step 4: Check the Size

Have the child put on the dress and gather the string to cinch the dress top. Tie the string to secure. Keep the dress loose and flowy. We also kept the hem unfinished for a spooky-cute finish.

Step 5: Make the Hat

Enlarge and trace the hat and hat brim patterns onto paper and cut out. Cut hat and brim from black felt. Sew the long sides of the hat together. Turn right side out, and cut slits to make tabs along the bottom edge of the hat. Place brim over the hat, sew the brim to the hat tabs, then sew a black headband inside the bottom of the hat.

Step 6: Make the Broom

Choose a stick that is fairly straight without branches; you'll want it to be about the same height as your child. Gather straw around the end of a stick. Wrap pumpkin-color yarn tightly around the straw to hold in place. For a sturdier DIY witch broomstick, use twigs and twine instead—you can even use it as a Halloween front porch decoration when you're not using it as part of the costume.
