I had a much easier time applying Forsythia than Fiona. Forsythia took three coats, and Fiona took four and gave me fits with streaking all along. It could be I got a bad bottle of Fiona; I might try adding some thinner because it did seem more gloppy than OPIs usually are.
With the shimmer vs. creme issue obviously these aren't dupes, but the colors don't quite match, either. Forsythia is darker and a touch more green; Fiona is brighter and more yellow. Both have that pretty ugly thing going on.
Reminder: You've got until midnight Eastern US time on Sunday, June 20th to enter my Wet 'n' Wild contest. My posting schedule will be a bit more erratic and sparse than usual between now and then due to my taking some time off to spend with family.
