This is a simple design made using striping tape.
I started by painting my thumbs in 2 coats of a gold shade.
On the remaining nails I used 2 coats of a dark shimmery blue.
On the gold nails I used blue striping tape and lay 4 stripes across each nail in a random pattern. Unfortunately my top coat faded the colour a bit on the blue striping tape.
On the ring fingers I also used 4 stripes of striping tape across the nails in a random pattern but this time I used a gold coloured tape.
