Having bought a house in the past year, I finally get to actually change things in the place in which I live. I'm reasonably experienced in some forms of woodwork but it has been quite a long time since I did any planing or polishing, so I spent something like an entire month making a single shelf. It's a pretty cool shelf though.
It's made from a piece of sycamore with a live edge, and was finished to 12000 grit because I was bored and wanted to play with some micro-mesh pads I bought. It's oiled using linseed oil, as that's what I use for spoon-carving and I had a load lying about.
The brackets, for reference, are from IKEA. They were cheap and relatively straight, and I'm quite pleased with them.
I had to plane it quite a lot on the back edge to fit against the wall, as it turns out the wall itself bows quite remarkably. It was a bit of a faff but it fits pretty closely now.
