Hi Judy....Ooooo decorating....my kind of thread!!! I think you and I are kind of in the same situation...although your place looks brand new! We just moved into our home in October. It is fairly new...only 15 years old.....We have been talking window treatments lately also! Our main room kitchen/living room has cathedral ceilings, is pretty open, well lit but it came with (what the realtor said were pretty expensive window treatments)--they are wooden blinds, very thin, blond colored wood....they are OK for now..but a little bleh....plain....but my husband is handy and I am somewhat crafty so we're thinking of making fabric covered cornices (for color) and then using sheers (for more light). I think it might do the trick!

JC Penny's does have some nice draperies also, but your're right it can get costly!! If you can sew at all, it can save you some $$!
