Happy Halloween!

The kids decided to dress up as King Arthur and Guinevere this year. {Check out this post for some of their past costume choices.} There was no way I was going to try to make a dress. That’s a little beyond my capabilities. :) But a knight costume, now that’s a different story. So, today, I’ll share how I made Nick’s King Arthur costume.

Knight Armor

Supplies needed:

  • paper bag
  • silver poster board/cardstock {mine was gold on one side and silver on the other}
  • hot glue gun
  • scissors


1. Cut the paper bag down the middle along the seam. Cut out holes for the neck and arms.

2. Create a template for the chain mail {approx. 3½” x 2½”}. Trace chain mail links on the back of the cardstock and cut out. {Since I want the silver as my front I traced on the gold side.} You will need approx. 70 pieces.

3. Start gluing the chain mail pieces to the front. Then to the back.
The links should slightly overlap. Work your way from the bottom to the top.

To achieve this pattern you will need to cut several pieces in half.

Supplies needed:


1. Start out by measuring the distance between the tips of the crown. I hope this picture illustration below makes sense. Then cut out.

2. Fit crown to head. Glue and staple along the seam for a strong bond.

Supplies needed:

  • aluminum foil
  • silver cardstock strip
  • printed dragon silhouette on cardstock
  • black construction paper
  • hot glue gun
  • duct tape
  • tape


1. Print dragon silhouette on colored cardstock. Cut shield form out of cardboard.

2. Cover shield with aluminum foil. I like to have the matte side showing. Use tape to seal edges and attach to cardboard.

3. Cut dragon to size and glue on black construction paper. Trim the black edges. Glue onto shield.

    Hi there. I made your costume, but my son can not seem to keep the armor on. How did you make this so it stayed? It keeps slipping off…

  • Monica

    My son still wears his costume and we have not had a slipping problem. Maybe you could add a ribbon on the back to both sides and tie it together. That should fix your problem. I’d love to see some pix! :)

    I figured out the problem. I made the hole for his head too big. I attached ties and reinforced the shoulder area and it worked rather well. If I could figure out how to post a picture, I would!
