I started with a base of Models Own Pear Purple, from the Diamond Dust collection. I then stamped using the Temix purple polish from this review post here, and MoYou London Festive plate . The plate is actually an Easter Egg design, but I think it looks abstract enough to be fine for non-Easter too!
I'm really happy with the end result.
My nails are getting really long recently too! Having said that, I'll probably break them all now...
