Tutorial to color blocked nails- paint nails white. once dry place a small sliver of tape on the edge of each nail. next simply paint a colorful polish over the white (try to avoid painting on top of the tape strip if possible, it will peal off easier if you do). After the polish dries remove the pieces of tape and voila, color blocked nails!

I think if you could do a cool nail thing and make the lipgloss one day the girls would love it, Sandi! its a good bonding activity. you could have them bring in their own nailpolish and use newspaper or try water marbling. ive done both of these and they work pretty good!
