As far as hanging curtains, instead of drilling a hole in the tile you may want to use these slide on brackets for mini blinds. It's a new product I came across. You replace the slide on thingys on your mini blinds with this bracket that holds single or double curtain rods. Thought it was a good idea since I hate drilling into the wall to set up curtain rod brackets. Hope it helps. Oh, here's the site http://www.slideonbrackets.com.

I suggest you cite your sources as a foot note. If you are unsure of what a foot-note is, it is a type of citation that is used. An site that uses a foot-note would be Wikipedia.

As you can see, there is a number after a certain sentence that looks like this [1]. That is an indication that that sentence is cited and if you click on the [1] it will take you to the end of the page where the sources are. If you'd like to do this type of citation, just notify me and I'll tell you more details. If you can't, then this site would help you with footnotes.
