This post is a bit late - either three days or one day, depending on how you look at it! I just wasn't really 'feeling it' this weekend, so I took some time off, even though I had these nails all prepped and ready!
I went for the fairly unimaginative henna tattoo design. I took inspiration from several nail art designs - I basically just put 'henna nail art' into Google images, and picked elements from various manicures.
I'm fairly happy with them - I didn't get as much swirl into the spiral as I would have liked, and I had terrible trouble photographing them, but they were very easy to do. The 'henna' is Barry M Red Black, and the base is Sally Hansen New Lengths in Sheer French Blush (an untried!).
