basically i left the bottom of the coasters their natural finish with a light sanding, this way they should have a little bit of grip on surfaces rather than slipping all over the table...
They seem thin enough so moisture already on the table shouldn't affect them long term... i have toyed with the idea of spraying the bottom like i did the top and sides with clear lacquer and scuffing the bottom half but that takes away from the fact that you can feel the natural banksia pod/nut and appreciate it's velvet fuzz so to speak....
Either way each one is definitely unique and no 2 could possible be the same :D
Anyway here's some pics of them finished... some of these pics are already in my latest pieces post from a while ago... also i have my whole collection on facebook...
