This is a super simple design that you could do for Christmas time due to the colours, or you could change the colours around for any time of the year.
I started by painting all nails in 2 coats of a bright red shade, except for the thumbs and ring fingers.
On the thumbs and ring fingers, I used a striping brush to paint a diagonal line in the same red shade starting in one corner at the base of the nail and ending about a 1/3 of the way down the nail on the opposite side.
I filled in the area closest to the tip of the nail in 2 coats of the red shade, leaving a small negative space area near the base of the nail.
On the same thumb and ring finger nails I first took a gold striping tape. I placed a diagonal stripe of this so that the line was coming from the opposite corner to the the line I had painted in red with the striping brush. I then placed a green stripe of striping tape just underneath the gold stripe, leaving a little space in between.
