The window (in my office) after installing the previously mentioned 2" faux wood blind and drilling through the PVC window sill.
Despite my best efforts, I could not find any DIY info regarding installing blinds with an inside mount to PVC windows on the internet. Aparently no one asks these questions.
My window folks said I could do it without voiding the warranty, but if anything happened to my windows which they deemed to be due to the installation of said blinds, the warranty would not cover it. Some help that is.
Alas, I must go and stare at my blinds.

Hey Jenn, I enjoy reading your blog. I don't always comment cuz it's sort of a pain going through the 'signing in' process, but I just want you to know that I'm reading - and I like the updates on your life!
