These are lovely.  The photo makes the pattern look a little busy.  It is actually more subtle and elegant.  Like all curtains they need some drapery weights to have them hang as straight as in the photo but the fabric is of beautiful weight and quality.  They do not block light completely.  They do, however, make the room as dark as any other "blackout" curtains I've seen, which is dark enough for me (and I tend to have difficulty sleeping with light in the room.)
