Leopard Nail Art ft Wah! Nail Pen

This week I tried out the WAH! Nail Art Pen, I've seen it used by a lot of bloggers to create leopard print patterns and lots of different designs on the nails. I'm not a nail whiz, definitely not, so I was a bit apprehensive about trying out this nail pen as it looks like you need a steady hand and general "goodness" of doing your nails. The nail pen has a tip which is what I used to create this leopard print design and also a very thin brush to create different looks.
I started off by painting my nails, then putting little spots on them with a different colour. To make the leopard print design, don't worry about the spacing and the shape of the spots you paint on as the more variety there is, the more it will look like a leopards spots. I then used the nail pen so just contour around the yellow spots, not completely just a little around the edges and voila! Simples. The nail pen was really easy to use, great results with no smudges and no excess nail polish coming out of the pen.
I got my nail pen from ASOS, it also comes in different colours.

What patterns do you like on your nails? Have you tried using a nail pen before?
