So I went to Target and got a $6 clip lamp and awaited inspiration.
Pinterest struck, as it so often does. I was able to pull the plastic shade off, paint the inside with tacky glue, and line it with gold glitter. Then I put it all together. The bulb casts a fairly golden light and I really like how the glitter brings it out. I have a gold lamp!
I also made madeleines in my new pan. I used this recipe and I think I'll keep experimenting. They tasted very nice and disappeared... really fast, actually. But they stuck badly to the pan and were more cupcake-like than I had intended. But still good.
