I do have a stamper that shrinks images so then it was a debate between shrink the image or use the clear stamper to neatly place the image. I went for the clear stamper and hoped to get enough image on the nail.
I uses Pet'la Cavaleras with A England Camelot over a base of Polished by Leanne Purity. Purity is a lovely white with a hint of shimmer (a bit camera shy when I took these pictures but nicer than just a plain white)
Then I coloured the images in with Sharpies.
They do look a bit abstract, not sure you would think "sugar skulls" if it didn't say that in the title but I did think they looked pretty.
