These wings are a mix of a two instructables with a dash of 3D printing.

While the wings are very cool by themselves, the real magic is wearing them at the Disney Parks (during holidays that allow adults to wear costumes, of course). The wings are made from vinyl, iridescent wrap, wire, and sparkle fiber optic wire. The harness is 3D printed, with the Made with Magic Minnie bows and AAA battery pack.

***EDIT***

I've added a YouTube video of the wings in action!

Step 1: Materials and Tools

Materials:

12 gauge wire
20 gauge vinyl
E6000 Glue (Really clear glue)
Masking Tape
Iridescent Wrap (NOT shrink wrap)
Krylon Spray Glue (Really clear glue)
Sparkle Fiber Optics (3 Strand, 0.75mm)
Black Thread
Instamorph Plastic (You don't need a whole lot)
AAA Battery Pack with Switch
Made with Magic Minnie Bow (Can be purchased at Disney parks)
Aluminum Foil (optional)

Tools:

3D Printer (or find a print service online)
Soldering Iron
Solder
Needle Nose pliers
Hot Glue
Hot Knife (or attachment to soldering iron like this)
Printer

Step 2: Sizing Wings

In order to decide what's an appropriate sized wing for you:

Find a wing design online or draw one
Upload to Rasterbator.net
- I would start at trying 2 pages wide
- Be sure to check what size paper it's using - default is A4
Choose No Effects
Choose Black and White
And Rasterbate
Cut the wing out and take together to try for size
Once you find a size you like, this will become your template.

Step 3: Cut Out Wings

Use your template to cut out your wings

Place the template under the vinyl
Trace with a sharpie or other marker
Cut out
Repeat for the other wing

Step 4: Straighten Wire

Cut a piece of wire that goes from where the top of the wing and the bottom of the wing meet about 3/4 of the way up plus a few inches.

Optional

How I straighten wire:

Take a small piece of 2 x 2 ( enough to fit in a vise)
Drill a hole a little bigger than the wire gauge
Place in vise
Stick the wire in to your drill chuck
Stick the wire through the hole
Slowly turn the drill on and slowly pull it through the hole

Step 5: Add Iridescent Wrap

You'll need to keep an eye on which side is which for this step.

Unroll the iridescent wrap on to a flat clean table
Tape the sides of the iridescent wrap to the table (a few pieces will do to keep it taut)
Spray one vinyl wing (not near the wrap please!)
Slowly roll the vinyl wing glue side down on to the iridescent wrap
- I found using a roll of wrapping pair to press it down gave the best result
Cut the wing out of the iridescent wrap
- It's OK to cut a little bit of the vinyl off as well to give it a clean edge

Repeat the above steps, but make sure you spray the OTHER side of the vinyl. When you lay the wings down as if you were wearing them, you want the iridescent wrap to be on the same side.

Step 6: Attach Wire to Wing

Hot Glue and Iridescent Wrap are not good friends

Take a craft knife and carefully cut a 1/4" piece of the iridescent wrap off of the side where the wire will go
- Be sure to only cut from where the top and bottom of the wing meet to the about 3/4 of the way up - the length of the wire to attach
Use masking tape to keep the wire in place along the wing
Hot glue sections of the wire
- I found pressing the wire down with the roll of masking tape helped it adhere
Once those sections cool, take the pieces of tape off and glue the rest of the wire

Step 7: Separating the Fiber Optics

The sparkle fiber optics come 3 strands in a vinyl sleeve.

Use a craft knife to carefully slice open the vinyl sleeve
Pull out the three individual strands
- I found it easiest to cut off large-ish sections and work with that

Step 8: Creating the Design

Now for the fun part

Place the template under the wing
- Make sure the vinyl side is facing up and not the iridescent wrap
Start taking your fiber optics and placing them to the corresponding lines on your design
- Use masking tape to keep the strands in place
Gather the ends where the top and bottom of the wings meet
- Keep at least 3 inches extra
- Use foil to keep them all together neatly

Step 9: Glue It Down

Once you've laid all the fiber optics over the design, it's time to glue it all down

Squeeze some E6000 glue out
Use a toothpick to grab a glob of glue
Start by putting dots of glue on all of the ends of the fiber optics to keep them down
- The ends on the vinyl, not the ones in the foil
Continue dotting the fiber optics with glue until they will not fall off
- See picture - not everywhere has glue. Just where it's needed
DO NOT glue right next the bundle of fiber optics in the foil. We'll do this in a bit

Step 10: Bundle It Together

Now that the design is permanently stuck, you need to create a bundle

Tie a constrictor knot around the fiber optics close to the wire where the top and bottom of the wing meet
Wrap the fiber optics bundle together until you have approx 2 -2.5 inches wrapped
Tie a constrictor knot to keep the bundle from unraveling
Use your hot knife to cut off all of the ends of the fiber optics
- Try your best to make this a parallel cut
- Do not cut the thread
Now go back and glue down the rest of the fiber optics close to the bundle (see picture)

Step 11: Repeat With a Twist

For the second wing, you're going to use the first wing as a template

Place the first wing fiber optic side down
Place the second (blank wing) on top, vinyl side up
Repeat steps 8-10 for this wing

Step 12: Create the Harness

First you need to disassemble the Made with Magic Minnie Bow. This is pretty straightforward - cut the bow off, take the plastic thing out, unscrew anything that has a screw, cut the wires.

Print the harness
Desolder the switch from the Bow board and toss
Solder the ground of the battery pack to the ground of the Bow board
Solder the power to the connection shown above
Heat the Instamorph according to instructions
Place the Bow board on to the printed harness as shown above
Use the instamorph plastic to attach the board
Use zip ties to keep the battery pack on the board

Step 13: Attach Stoppers

I found that the fiber optics tend to pull the wings together, to combat this, we add "stoppers" to keep them from moving so much.

Print two stoppers
Slide the stopper up the wire to sit next to the fiber optic bundle
Place the wing and bundle in to the harness
Adjust the stopper so the wings sit at a desirable angle
- You may need to sand the stopper down a bit
Mark where the stopper should go with a sharpie on the wire
Use JB Weld to keep the stopper from moving

Step 14: Go Forth!

And that's it!

The harness works by weaving a bra band over the wires and under the battery pack to keep it close to the back. The IR sensors in the Made with Magic Minnie Bows are able to receive signals through fabric and will interact with the shows and rides in the parks!
