Hi All,

Baking paper musty have a special name in the US, but the post I read here
(which I thought was from one of the "heavy regulars" like Greenfield or
Delorie) said it was silicon impregnated. Australian baking paper is
available in supermarkets near where the tin foil and cling wrap live (and
is dispnsed similarly on a roll) and is wayyyy cheaper than the Silpat
mentioned.

As ever, wikipedia has some good info (more than I knew):
http://en.wikipedia.org/wiki/Baking_paper

Regarding the hills or valleys, it would appear to be, um, thinned - looks
like some of the edges are sticking to the paper, not the board, which I
suppose could be down to them not being pressed against the copper. 'Cos I'm
making them so small, it is hard to drag the edge of the iron over the
board, which is what I normally do to get higher pressure.

Regarding brother-or-not, what I was trying to say is "the HP's able to fuse
this toner, so it probably can't be that different a melt-point"

Thanks for all the follow up. For folks about to try it: I don't think it
would be a good idea to stick a whole A4/Letter sized sheet in yr printers
solo, it's very thin. What's worked for me is an "island" of the stuff,
taped down on the leading edge
