This simple Lavendar lace design can be found on image plate M71. You can choose to paint your nails in a light base of your choice. You can also do this in dark colours for a different look =]
For this specific design, use a light purple special nail polish for the full pattern on the top right corner of the image plate. If you don't have light purple, you can also mix blue, red, and white to get a similar colour.
Then use the white special nail polish for the lace on the bottom right on the image plate. Place the lace diagonally across the tip of your nails. Put on some top coat and let your nails dry =]
