Now everyone thinks it is hard to turn a small item inside out. but it isn't if you know the technique.
Here I stick my finger into one side of the wing. Then I put the tip of my scissors against the end of my finger. If you don't want to use scissors you can use any turning tool. I have seen people use a straw if you don't have a tool. Then I slowly pull the edge of the wing down over the tip of the scissors. Til you have it all the way turned.
