I washi blocked and acrylic painted, adding Glitterific Paint to the green section and Glitter Glue I found at Joann's for the purple.
Now the stand ended up being top heavy so I added an extra layer of thick chipboard on the base and didn't lock the back flap in. It basically stands straight up (stuck down with Scortape).
I wouldn't make a stand this tall in the future, just because I like to lock things in.
It makes me a little twitchy that it's not locked in, but it's not going anywhere and shouldn't fall over since I ScorTaped it with a 1/8 inch strip.
