With every project, once it's done all I see are ways to do it better and production flaws. But I think with both of these, it's about seeing how to make them simpler. They work well enough - especially the lamp as a lighting piece that isn't hardwired that can plug it into the wall outlet - but while I like the Fibonacci spiral motif, you can use fewer bulbs and less math and still make something that looks good.
Same with the wine rack. This really is a bit too Keebler Elf. But I do like the idea of wine on the wall and plan to revisit the idea and play around with that more in the coming months, with simpler, more elegant designs. Just less.
