NONONO! It is not wax paper. It is NOT anything like wax paper. Wax paper is used to wrap sandwiches and stuff you do not want to stick to the paper. Wax paper is paper covered in wax.
The terms are not interchangeable in different countries.
Baking paper is NOT waxy. It is not covered in wax. Water does not soak into or through wax.
Baking paper is used to BAKE. It is very different. The only similarity is that it comes in a box on a roll. Baking paper is used to keep cookies and stuff from sticking to your trays or oven racks or drying/cooling racks.
I\'m not really all that excited here, I just wanted to make it clear that wax paper is nothing like baking paper or parchment. It will be in the same section of the store, it will look the same being in similar boxes, but the contents are VERY different indeed.
Anyway, having said all that, I\'d suggest going to an Arts and Crafts store and buying a wet palette. You can get smaller ones, although even the \"minis\" are fairly HUGE for our purposes, 8x4 or 9x5 inch type deal. Personally I like this size range, I can use the one for all the projects I\'m working on. While one unit dries or is on hold waiting for me to decide I can work on the next, and the next, and the next, without running out of room or wasting paint due to drying out. Anyway, the point is, they\'re cheap, the replacement paper is cheap, the replacement sponges are cheap. Not as cheap as baking parchment of course, but they are of a substantially higher quality for the slight increase in cost. The stuff from the art stores lasts so much longer before it breaks down. You really don\'t want bits of paper in your paint, or worse, on your model.
For example, the one I got from an art store called Wallacks here in Canada:

So that\'d be around 5 or 6 pounds, not accounting for shipping, for the UK crowd I guess? Not that I\'d suggest buying from North America if you live there, but to give you an idea of the cost.
A drop of vinegar, bleach, antibacterial dish or liquid hand soap, a couple drops of lemon juice or the like in the resevoir really helps the \"funk\" factor, especially when you\'ll be closing up shop for extended periods.
