This started out as something completely different in my mind, but this is what it blossomed into.  There is a black sparkly background (not that you can really tell), then I splattered over it (using the drinking straw method) the orange, then red, and I finished it off with some white stitches.

After I posted my Star Trek nails to Facebook, I got an amazing suggestion to add Worf's baldric. So here it is!

I taped off the area for the baldric, and used one of my Mash stamping plates for the chain pattern. Finished it up with a few minimalistic badges with a dotting tool, and voila! Worf'ed!

Tools Used:

Scotch tape

Mash plate #41

Polishes Used:

Dark - Sally Hansen X-treme Wear #22 Gunmetal

Light - Sally Hansen X-treme Wear #220 Celeb City

Yup, I've gotten into Star Trek:TNG. I'm currently on season 3 marathoning my way through while doing my nails.

Here's my representation of the typical away team: Riker, Data, Geordie, Worf, an Dr. Crusher.

This is my third attempt at galaxy nails and it is by far my best.  I recently got my order of MoYou nail stamping plates which included a sci-fi themed plate, and this was a good design to use to break them in!

I took pictures of them with a flash and one without and I couldn't decide which one I liked best.  So here's both!

This weekend was the Minneapolis Comic Con.  It was quite the spectacle.  I picked up some bitching prints, saw some crazy (and lazy) cosplayers, oh, and I got my picture taken with Nathan Fillion!  Obviously I had to paint my nails to match the occasion, and after watching the entire Firefly series while I was off work being sick, naturally I decided to do Firefly inspired nails.
I had to keep it simple because I still was not feeling well.  So, I ended up with a gradient of Jayne Cobb's hat and did a simple line drawing of said hat.
This picture was also taken after a few days of wear.

Make-up sponge

I decided to do two accent nails based off my tattoo.  I accomplished this look with a variety of blue acrylic paints and mixing up my own pinks, and a variety of liner brushes.  I'm sure you could do this with nail polish if you have the right colors.

Small & medium liner brushes

There are two different ways to get the Tron look on your nails: 
1) You can free-hand, which is what I did  or 2) you could use striping tape, which I didn't have on-hand. 
 
I decided that I was going to use my nail art pens for these since they are easier to control for straight lines, but I encountered a problem - the blue pen didn't show up on top of the black.  To remedy this, I simply drew the lines first with my white nail pen, waited for it to dry, then colored them in with the bright blue.  Boom, Tron nails.

These pictures are pre-clean up.
Also, I'm going to include pictures of both of my hands.  Try to guess which is my dominant hand ;)
