If someone could bash out a white "jig" for anchor placement we'd be happy to host it. Like Brant says; basically a template with holes cut out where you can mark with a pen or pencil. You could even use a tack to punch holes in each corner of an anchor marker, then stick a pen or pencil in there to mark the tile underneath. You could even build the jig with a sleeve so that it smoothly slides over the tile and prevents it from moving around while you're doing your marking.

I would do it myself but I'm overloaded at the moment.

Okay, so here we go (right click onto the picture to download the pdf):



Please let me know if everything works as it should, I don't have the chance to test it atm (no money for foamboard...).

Thanks Zaphlo, I just downloaded it and when I get home this afternoon I'll print er off, glue em together and see if they fit around some tiles

I was just wondering how i would line up the anchors to put on some Canals tiles so that I could make good use of the outflow walls - and now I know!
