I ended up with two small "trays" and the colours left something to be desired.
The Lemon Lime one got a bit toasted too. *sigh* But, all in all, I did learn some very valuable lessons.
The good news is, my son really liked the small Cafe Latte one and has appropriated it for his nightstand. Also, my little black buttons turned out really well.
Today, I am drawing new blueprints for my boxes, and have made some more buttons. I have also tried a couple more experiments. I will let you know how those turn out!
