Marcia, I put the original photo into photoshop and then I "skewed" it until it was perfectly square. Then it was just copy and paste.
I'm not sure about gold, I was just working within the parameters of the fabric she's already got. I kinda think gold would overpower the rest. Navy blue (a lighter than almost black) would look well with these colors. That's what I used in my batik Seminole patchwork jacket
