I have blinds - makes it easy to adjust the sun coming in during the afternoon time. I have floor length curtains that hang on the side of the windows (tab tops with buttons) for color. I bought the curtains at Bed and Bath. I would rather quilt than make curtains. lol Someone on the board mentioned once that asking a quilter to mend is like asking Van Gogh to paint the house - not quite the quote but you get the idea.
If you like making curtains by all means make them. If not, buy them... you can get them for all prices, colors, etc. at many different places.
But most important - have fun!
