A lot more than what I expected.  I bought two for my kitchen in the Wheat and they block out a good amount of light and heat and they look cute!  The material is thicker so tying and adjusting for the perfect look may take an additional minute or two. 
I plan on buying six more for my mudroom.  I gave it four stars instead of five because I'm unsure on why some of the colors are at least $10 more than the other colors.
