Went to goodwill and found clothes that looked like they could be reconstructed into a cape, boots, and gauntlets..
Step 1: The Cape
I split the big velvety dress in half, cut off arms and sewed up the armholes. I folded about an inch on each side and the bottom, pinned and sewed to create a finished edge on each side. I folded the top down about 2 inches and sewed, leaving an opening on each end to fit a ribbon through, so the cape could tie together. I drew a pointy hood pattern on paper, then used the leftover fabric from the arms construct it. I lined the inside the hood with fabric from the wooly green jacket,and then used a bright green ribbon to line the edges and make it pop. I also cut slits in the hood for the elf ears.
Step 2: Shoulder Armor
I split apart an old purse and cut out almond shaped pieces that I thought would work for a layered, leather armor piece. I machine stitched them together only where the tips of them met together so it would maintain a shoulder armor shape. I used the shoulder straps of the purse to hold the piece together on my daughter's body. I bought a gold marker and created a design that I though looked elven.
Step 3: Arrows
My daughter collected goose feathers this summer. We spit them to make the arrows and glued them to dowel rods. The quiver was cardboard. I shoved a fun noodle in the bottom of the quiver to hold the arrows, then threaded the goodwill belt through two openings I cut in the cardboard, so it could be worn. The quiver was then wrapped in green rope.
Step 4: Ears & Hair
I bought WoW Night Elf ears and fixed them in place with spirit gum. I bought a $10 red wig from Amazon.
Step 5: Boots and Gauntlets
I split the brown pants and created a pattern for gauntlets and boots. I straight stitched them together.
