Wood or Fauxwood a question we are always asked, both are great, but in Bathrooms and Kitchens Fauxwood is the preffered option as it has less tendency to warp than Wood.
As with all natural products Hot and Cold tempretures play major part in how they react so always bear that in mind when choosing your blinds.
The other big question, with Tapes (as in picture 2 ) or without tapes, well this really comes down to individual taste, however the benifits of tapes are more light blockage ( the tapes cover the punch holes) and therefore more privacy and some say more stylish, you can change the whole look of the blind by going for a contrast colour with the tape.
