Hello,


#declare Bedsheet = "images/cloth15.jpg";
union {
 smooth_triangle { <-90.0829, 10.6486, 90.5189>, <-0.938913, 0.0928805,
0.331385>, <-90.8569, 12.819, 87.3967>, <-0.966925, -0.0604885, 0.247783>,
<-90.6256, 10.7625, 86.4407> , <-0.979818, -0.175934, 0.0948896> }


      texture{
          pigment {uv_mapping image_map {jpeg Bedsheet }}
      }
}

here is an povray output: http://www.css4me.com/test/pov/bed.bmp
and texture: http://www.css4me.com/test/pov/cloth15.jpg

My guess is that your triangles have no uv-coordinates. They should look 
something like this:

smooth_triangle 
{<0.480625,0,0.1>,<0,1,0>,<0.680625,0,0>,<0,1,0>,<0.680625,0,0.12253>,<0,1,0>uv_vectors<0.387569,0.545324>,<0.5,0.770187>,<0.362238,0.770187>}

An union of triangles? You should replace union by mesh.

Thanks my problem is solved by using mesh.
