I started with a white base for these (Island Girl Pineapple Plantation) and then got to work with the Sharpies and rubbing alcohol. I think I used quite a few pinks and purples and blues (my favourite half of the color spectrum) and just kept adding to it until I thought I had something that resembled flowers.
For the centres, yellow sharpie wasn't colorful enough so I used a bit of alcohol ink there. And then used black sharpie to add the dots in the middle.
While my Sharpie flowers didn't turn out exactly like the inspiration photo, I hope they're close enough to pass. I'm pretty sure the inspiration dress is one of those crazy cheap dresses from overseas that, if you ordered it, you may or may not receive and it may or may not be anything like the photo but it did make good nail art, haha!
