One design that could be used for Halloween ->
I used Bluesky gel polish 501 for the white base and Bluesky gel polish stripping pen 02 for the black lines.
The skulls and the flowers are hand- painted with acrylic paints.
Another variety of this design is this one ->
It`s without the skuls and only 4 nails white polished with lines and flowers. Others are only with black lines over the gel- covered nails.
