If names matter, then the Rebeca Solid Blackout Thermal Rod Pocket Curtain panels have set a high bar for expectation when it comes to draperies.  Solid.   Blackout. Thermal.  Declarative, powerful words that serve to create a narrative of London during the Blitz.  Blackout regulations were imposed on 1 September 1939 because the UK Air Ministry did not play.  Sadly, these Rebeca curtain panels wrote a check that they could not cash.  Solid?  More like solidish.  Blackout?  Hardly.  Thermal? M'eh.  They're decent, serviceable, and are pleasant to look at.  I'd advise the copy writer to rename them to Rebeca Translucent Greyout Thermalish Rod Pocket Curtain Panels.  If you're serious about your sleep hygiene, need your room to be the darkness level of Plato's cave, you're going to want to upgrade from these.  If you're looking for "good enough," then these will do.  3 stars.
