Homebrew PCBs

I saw this mentioned recently and thought I'd give it a go. Here are some findings and some questions

I'm having no problems getting the paper thru the printer: I just cut a section the size of my board and tape it onto a printout of the board on full-size paper (so it's positioned right). I tape only the leading edge and so far it's been fine. (I should add that, in order to preserve my materials for as long as possible, I make all may boards as small as possible and the paper's never been bigger than about a credit card).

Removing the baking paper is a joy - just peel it away, but I am noticing that the edges are very rough, and if I hold the baking paper to the light, there are some very tiny traces of toner left behind on the edges. The complicating factor is that the very same time I started using baking paper, we went started a new generic toner cartridge, but I thought I'd see if anyone had any experiences.

* has anyone seen a particular toner produce rough edges? It does appear pretty good when still on the paper
* Would baking paper require a higher heat? I've been increasing heat and time but no change yet (as always, we're talking a fairly small sample here)

What does that brother toner look like when improperly stuck? This toner sticks to paper perfectly well, so I don't think it's radically different.

(printer's HP 5MP and I'm still using the iron)
