How to Make the Gun Holster

Before making the gun holster, make sure you’re working area is neat and clean and away from children. You’re dealing with chemicals that children might ingest so be extra careful and prioritize safety.

What Materials to Use

  • A stiff black fabric
  • Silver acrylic paint or round silver studs
  • Black thread
  • Large ring (any color)
  • Any type of sealer
  • Pencil for sketching out the design

Step 1

First off, measure from the middle of your chest to the middle of your back then double that measurement. If you find it troubling, have someone measure it for you.

Use the measurement you got to cut 4 pieces of the stiff black fabric. It depends on you how wide you want it to be. I recommend a width of 3 inches or more for better durability.

Step 2

Stitch the pieces together to make 2 solid straps. Loop the ends of the straps through the large ring and stitch them to place.

You can go and add painted dots using the silver paint to the straps. You can also use silver round studs and stitch or glue them on the solid straps for a better similarity to the Harley Quinn gun holster.

Step 3

Using your Harley Quinn toy gun, place it on top of the stiff black fabric. Trace the gun from the hammer to the middle of the trigger guard (this will be the pouch for your gun). Make sure you leave some room to stitch seams together and cut out 2 pieces.

Sew them together on only 3 sides to make a pouch. Make sure to fit the gun in before sewing them together if the gun really does fit in.

After making the pouch, stitch it to one of the straps to complete the Harley Quinn gun holster.

Step 4 (Optional)

Cut out 2 pieces of about 7 inches long by 3 inches wide, and 4 pieces that are 5 and a half inches long by 3 inches wide. Make sure you add a bit of seam allowance for the stitching. Stitch them together to create 3 solid pieces.

Stitch one of the smaller pieces to the top and middle of the bigger piece, creating a B shape. Do the same for the remaining small and big pieces. Stitch the top of the bigger piece to the holster strap and you got yourself a grenade pouch for your holster.

How to Decorate the Gun

Harley Quinn’s gun isn’t just an ordinary gun. It has full of decorations that fit her personality. You can’t complete the Harley Quinn Gun Holster without the signature gun Harley Quinn uses.

What Materials to Use

  • A toy gun
  • Black acrylic paint
  • Gold acrylic paint
  • Tacky glue
  • White fabric paint
  • Any type of sealer
  • Foamboard
  • Hot glue gun
  • Pencil for sketching out the design

Step 1

First off, try using the super glue to glue the cylinder of the gun down and keep it in place. If using superglue isn’t enough to stick it, then use a hot glue stick instead.

Since you’ll only be cosplaying as Harley Quinn, you don’t need the Cylinder to load up bullets. Unless you’re using a toy gun that has features that will improve your Harley Quinn costume.

Step 2

If your gun has grooves on the handle, fill them up with white fabric paint or tacky glue in order to even the surface. This will be useful in the following steps as you need the groove to have an even surface.

Step 3

Paint the handle of the gun with the white fabric paint. Make it look as smooth as possible.

Step 4

Cut out 2 pieces of foam board and make them into a shape of an extension of the barrel of the gun. Make sure to trace a sketch of the barrel extension. Have a copy of Harley Quinn’s original gun as a picture reference. Afterward, glue them together to increase the thickness.

Glue them under the barrel of the gun to act as a barrel extension and make it look larger. Paint the whole gun black except the handle, trigger, and hammer.

Step 5

Now, this is the trickiest part. It isn’t a Harley Quinn gun unless you have the jester emblem on it. You need to place a jester emblem on the handle of the gun. You can simply do by printing a jester or joker emblem sticker and stick it on the gun handle.

If you want a more realistic look, layer up the fabric paint according to the jester emblem and wait for it to dry.

Step 6

All that’s left to do is finish up on the details. Make sure you have detailed reference pictures to copy from. Write Love and Hate on the cylinder and paint some golden diamonds on the barrel of the gun.

Add up additional designs according to your preference and you’ve completed making the Harley Quinn Gun Holster.
