These simple bat wing earrings are meant to be printed with tulle fabric added halfway through the print. I actually think 4 pieces of tulle added in looks best. You can see that in the third and last picture where there are two wings with 1 tulle piece and two wings with 4 tulle pieces.
You have to trim all the tulle off the edges after, it can be tedious.
Once printed and trimmed, attach to chains and earrings.
You can iron the top layer, but I don't think you have to unless you were to print these in a lighter color.
[Also looks good printed in gold with tan tulle.]
