This one doesn't need any explanation other than "inspired by Robin Moses". She made the video, I copied, only I changed it to purple and green. Also, I should mention I did this all with a toothpick, mostly because I'm lazy to get my brushes dirty sometimes. Most times, actually. Also should be mentioned that this design would look really pretty on short nails.
I did it long ago so I'm not sure anymore what colours I used, but the ones I remember are these:
Essence 58 The one and only (light purple flowers)
Claire's anon random mate (medium purple flowers)
Rimmel 406 Purple Addict (dark purple flowers)
Essence 43 Where's the party? (purple base)
H&M Hunt Me Down (green base)
H&M No Mambo Jambo (green flowers)
And I'm ALMOST sure that H&MxHello Kitty Turquoise and Kiko 389 are also green flower colours, plus a couple others that I don't remember anymore. I don't remember what the dot colours were either.
