Plaid? Gingham? Eyelet? Chintz? Toile?

Eyelet

External shutters with gun slits, and patchwork curtains made from grandmas old bloomers lend that sense of family continuity.

Hubby says not so good if grandma is still alive

Do you have any pictures of such patchwork curtains?

No, baby boomer grandmas of today wear small undies and ride motor bikes. According to the horror movies , the bad guys burst through the windows of cabins while the family is playing scrabble, so I recommend the gun slit shutters which would also keep out bears. In Australia we have to contend with drop bears and must wear akubra (cowboy) hats while shopping. Your other option is not to play scrabble, then you can have some lovely curtains from Liberty of London, Laura Ashley, Designer Guild fabrics or similar

Have you considered no curtains and putting the money into beautifying the windows instead? Some of the most beautiful log cabin photos I've seen have no window dressings. Of course this only works if you don't need privacy.

Agree with bumblebee but get double glazing for the cold

If getting curtains for insulation have them lined, and down to a flat surface such as a floor or window sill. Then put a pelmet above the window to stop warm air escaping.

Burlap drapes from Pottery Barn.

These are not curtains but I saw this and had to share it because I think it is a brilliant idea !

Cool, mark

How about just wood blinds? If you post a pic, we could collectively come up with good ideas for you. You don't have to go country in a log home ...

Cool

Chookchook2, here's a dilemma that might interest you, it always needs advice :)

Sylvia, I think that curtains or drapes made from matelasse coverlets or from simple thin quilts are quite lovely for a log cabin, plus they're thicker and more insulating when pulled closed. :)

Like your ideas mforr, we have used nice blankets while waiting for curtains and quilts are just as good insulators.
