Did you guess? Yup, I went with the silver pleather. The black just seemed to contrast-y and it seemed like the perfect opportunity to use silver pleather. I mean when else except Halloween and maybe dress up can you say that? I still used the black felt, but more as a stabilizer in between each of the wing layers.
You can see it's not perfect. There's all kind of puckering on the bottom wings where I have pleather on both sides (the top wings are pleather on the back). I should have busted out the walking foot, but my internal dialog went something like "my sewing machine handles this stuff really well". It did - when there was one side fabric to help smooth things along.
Regardless of the imperfections, I still love them! Now I can't wait to pull the whole costume together and see my two ladybug girls on Halloween!
