The most fun I've had making string art to date. Yes, I say that about a lot of them, but it's always true. The flowers were made out of the ends of the strings, in the same color-coded order as they were on the guitar: gold, red, black, green, purple, silver. To me, it's like the flowers are dancing in the lightning storm, without a care or worry in the world.

It's a wooden canvas, stained white and set in table-top epoxy. Demensions are rougly 18"x11"
