Right, I remember!
One thing I thought of for a bat face would be to get a fox mask and then paint it black or brown. Since bats are known as "flying foxes" and have those foxy little faces.
I am the luckiest girl in the world. The mermaid costume is coming along but I just haven't been able to figure out what to do about the front -- keep it as stupid foam fake purple seashells (no), take those off and replace with real shells (maybe -- problems include color [too flesh-toned, really don't want her to look topless] and hardness/pokiness), or maybe try to make one of those more continuous costumes, more like an evening dress, rather than a bare top and the scales starting at the waist. (Ya know?) Problem there was what to make the top part out of. I was thinking of cutting some out of the sides of the dress where the "fins" come out, but there wasn't enough and there would be a seam and...
Anyway, I was fretting and plotting and then went to JoAnn fabrics to get various items. (Wire, fake pearls, green polarfleece for the seaweed cape, etc.) There... right in front of me when I walked in... and 60% off... was the PRECISE fabric used in the costume!!!!! I mean not the same idea or something, THE stuff. Exact match.
Then on the same display stand was this shimmery liquidy blue stuff -- great for a "water" cape.
And made by the same company (Disney, as far as I can tell) and from the same collection, I'd guess, so it "goes." Similar weight, sheen, etc.
So I got some same-colored polarfleece to line it (partially, the bottom part will be single-layer, just the watery fabric), and I'm set.
I was thinking of cutting flippy watery edges -- like cresting waves, crescents -- but the other side of the watery fabric isn't great (just flat boring blue, and not a great blue), so I think I'll just do an undulating edge. It'll have lots of movement when she walks.
I also got some super-cheap but REAL starfish and one little REAL seahorse (a dollar!) at a local store. Those will go in her crown thing.
This should be fun.
