Now you are, done all you have to do is leave your feather somewhere to dry for 24 hours. After which it should be hard enough to turn over and allow another 24 hours to dry. These times are a minimum and they should be left in a dry, not too cold environment.
Once they were all dry, I painted the tips with black food colour, but that was what I wanted, you may want something different. If you do need to paint your feathers, make sure you keep the colour thin as too much will make the Sugar Paste soft and can cause the feather to bend or break.
