No, they are not the rolly up ones - they have that pully system that sometimes works, sometimes doesn't
I have decided against buying a drill and decided instead on putting them up with <mumble mumble> string.
Mimi logic:
String (<£) > drill.
String for the win!
I have just put the first up and it looks aceness. I am going to have lunch and then put teh second up. They are blackout blinds, too - so no waking up at 3:30 am for me, tomorrow!
EDIT:
Oh, big hugs, curiosity! Less fretfullness is definitely better than string.
