I went to the hardware store and picked up a nice white, glazed ceramic tile that is about 4x6 for less than a buck and it works great. You have plenty of room to mix on, and if it gets too gunked up you can takea razr blade o it and it\'s good as new. The white also lets you see your colors well and, as long as you don\'t drop it, it\'s quite durable.
But I also have several \"recessed well\" pallettes for very fluid wash mixes. They do have a tendancy to save my denims from a multi-coloured bath now and again.
Never used a wet-pallette, but then again I can\'t wet blend.
CD-Roms.
My Dad had the habit to collect CD-Roms he doesn\'t need - AOL giveaways, failed burns, the CD\'s that come with magazines, ... giving me a virtually endless supply.
