I have vertical blinds I want to take them down and put up room darken

you need ti decide what type of rod you want. There are types with decoration on the ends, those sit in a a holder that is cupped to fit the rod. Then the standard curtain. The rod has curved ends to hook onto the provided brackets, will hold the curtian, some have double hooks for a shear curtian under, then there are the draw tyep..pull on a string to open the curtian, usually split in the middle and half the drapes go to the right, the other to the left. And yes you will need a screw driver to put the rod holder to the wall. And depending on the length of you window you may need an additional support for the middle. Now..the best room darkening curtians I’ve ever had were sewn with a warm windows products found at major fabric stores, the big M isn’t one. Fabric shop j.a. Or mail order. Unfortunately for me none from my previous house fit my currant windows

I would borrow a drill, find studs and secure properly. Or get someone to help you.

What type of rod do you want? The choices (and prices) are almost limitless. Do you want to make the curtains yourself or purchase ready made?

When choosing ready made curtains or drapes, I purchase those first, then the appropriate rod to go with them. Here are a bunch of links for examples.

That depends on how heavy the curtains are,and if you want a inside point or a outside mount

Thanks for everyone’s input!

Probably a drill to install a rod.

if you are not ready to attack the "drill" idea yet:)...you can always get a tension rod for the time being..I use them on most of my windows cause I hate to make holes all the time.

It may be just me, but I hate to drill holes in wood frames around windows and doors. I would use a tension rod unless there were already attachments there for hanging curtains/drapes.
