Give your tree invincibility with this glowing Super Mario Starman tree-topper. It's simple to make with some basic sewing knowledge and utilizes LED Throwie technology. Even if you aren't a gamer, this cute plushy star will light up any Christmas!

Step 1: Materials

This project is made in two parts -- the plush and the electronic. It could be made equally as cute without the electronic part, but really it's so simple, there's hardly a reason to skip it! You'll need:

Vinyl: yellow (approx 2 sheets of 8 1/2" x 11"), scraps of black and white
Glue
Batting to fill the star
Needle & thread
Coin cell battery
Two yellow LEDs
Stranded wire
Tiny switch
Filament packing tape
Sewing machine (opt)

Step 2: Cut the Materials

To make a pattern, I simply printed out an image of the Starman that I found by searching online. It doesn't have to be high-res, you just need to stretch it out to fill a page.
Otherwise, just cut out a star shape from some paper.

Trace pattern onto back of yellow vinyl with a pencil. Add a 1/2" border all the way around for seam allowance.
Cut two of these stars
Cut two eyes from black vinyl with no seam allowance
Cut two tiny ovals from the white vinyl

Step 3: Glue on Eyes

I found it easier to put the eyes on before sewing, since I could lay the vinyl piece directly over the picture I printed out and get the placement exactly right.

Lay vinyl face-up on top of pattern
Glue black eyes directly over placement on pattern
Remove vinyl from pattern to see where to glue white ovals

Step 4: Sew Star

Place the two vinyl stars together, face to face.
Pin along the stitching line you drew
Using smallish hand-stitches or a sewing machine, sew ALMOST all the way around the star, pivoting at each point, and leaving one side of one point open so you can turn the star right side out
If you're particular about these thing, as I am, go back and stitch over all your points and inside corners again. We're going to trim away the seam allowance, and this will help insure that the stitches at these places don't pop
Trim away excess fabric at points and inside corners so it will turn right-side out nicely and won't bulge at the points or pull at the corners
Turn your creation right side out

Step 5: Make a Throwie - Add a Switch!

Using the diagram that Randolfo made me and the LED Throwies instructable, I was able to make a super simple device for the inside of the star. Granted, it took me three different versions to land on this most basic one, but it was well worth the learning.

Test your LEDs: The longer LED lead, called the anode, should be touching the positive terminal (+) of the battery and the shorter LED lead, called the cathode, should be touching the negative terminal (-) of the battery.
Check out Randolfo's diagram for a clearer picture of what's about to happen.
Twist together the two long LED leads (anode, +)
Twist together the two short LED leads (cathode, -)
Cut two small lengths of wire. Solder (or just twist super well) one end to an outer switch prong and the other end of the same wire to the shorter LED leads (cathodes, -)
Take the other wire and solder to or twist it up with the middle prong of the switch
Cut a piece of tape about 8" long. Tape the longer (anode, +) LED leads to the battery by wrapping tape 2-3 times around both sides of the battery. Keep the tape very tight as you wrap.
To make the unit more compact, loop up any extra wire and tape to the battery as well. (opt) [see 1st picture in step]

Step 6: Stuff Your Star

Time to pile it all in! Grab that beautiful star you just made.

Stuff star with small bits of batting, and use a pencil to push into the corners
Add some more stuffing to fill out the middle a bit
Insert the LED unit you just made, making sure the switch sticks out
Turn the LEDs on to see where you need more batting
Finish stuffing star and align switch with opening in star
Hand sew the opening of the star shut, running it through the little holes on each side of the batter to keep it from slipping back inside

Step 7: Place Wherever Invincibility Is Needed

Finis!

This star looks great in combo with the 1up Mushroom Ornaments!
