I didn't take step by step pictures, but really, it was quite easy!
I started with the cupcake toppers.  There is very little in the way of party supplies for Legend of Zelda.  My 10-year-old loves his video games and so we worked with what we could find.  I ordered some Zelda stickers online and got some dark green card stock.  I used 2 squares per topper and 2 stickers.  Some of the edges of the squares I used crimping sheers, but frankly mine weren't very good, which is why I only did half that way.  I put the sticker on the squares put a toothpick in between the squares and used some hot glue and voila, cupcake toppers!
I had some left over strips of the card stock so I decided to use the scraps to make a little banner to add some green to the party decor.
Simply cut your card stock rectangles approximately the same size and cut a little triangle on the bottom.  I threaded mine with an embroidery needle and some baker's twine I had (shhh, don't tell anyone the twine was red and white and our party colors were green and yellow!)
My cupcake stand was 2 old ironstone platters with an upside down cup in between.  My husband thought that was rather redneck, but I thought it was cute :)  Green and yellow streamers, green and yellow balloons and 8 boys.
There you have it!  Easy Peasy Zelda Party!
