I made rose water the other day and I wanted to write the recipe here, so I don't forget :-) I'm fortunate in that I have a variety of roses growing outside my house - so I can make rose water for free :-)
Instructions
Put 1 packed cup of rose petals in a heat-resistance bowl. Cover it with 2 cups of boiling water. Cover the bowl and let steep for 30 minutes. Filter the liquid with cheesecloth into a jar, discard the petals & cheesecloth and cover the jar. Add 1 Tbsp. vodka and/or keep in the refrigerator. It should last about 10 days.

This rose water is not for consumption. If you want a cooling and exotic rose water drink, try this one.
