First time fabric painter! Nervous! Advice?

Are there any noob mistakes?

It doesn't LOOK complicated, but many things in life have depth to them that goes largely unnoticed until it's too late 😅

What would be most helpful imo would be something like that thing tattoo artists put on your skin before they use the needle.

Like, is there anything not permanent I can use to draw on the fabric first and have the outlines done, then trace them with the paint?

The fabric is 100% polyester, it's satin, and it's red. I'd call it candy apple red.

If it makes a difference, it's the shinier side I'm gonna be drawing on. I noticed the other side is more dull. Might have different physical properties.
