Claim 14:
15. A woven papermaking fabric comprising:
a. a pair of spaced apart machine direction (MD) oriented protuberances formed from two or more woven warp filaments and having a non-zero element angle and an upper surface lying in a first fabric surface plane;
b. a pair of spaced apart cross-machine direction (CD) oriented protuberances formed from two or more woven shute filaments having a non-zero element angle and an upper surface lying in a second fabric surface plane;, wherein the pair of MD oriented protuberances and the pair of CD oriented protuberances intersect one another and bound a discrete valley having an upper surface lying a valley bottom plane and wherein the valley bottom plane is below the first and second fabric surface planes and the discrete valleys have a depth of 0.5 mm or greater.
