How can i create tinny object .for example bird feather, dress smock and flag.they are very thin.

make a square ( 2 polygons ) copy it, flip the normals on the copy. weld togeather each coorisponding vertex, thus making a 2 sided flate surface. then you UV map as normal

I guess I must be lazy, but to create a "flat" square I just create a cube then select one of the faces and push it up against the other face (very very close together). It works for what I've been doing (which is making an invisible square that I can place on top of other entities so that the invisible square can be clicked on by the user.

same thing. i usualy take the cube and weld verts 4 times (0nce for each corner)

just didn;t want to make it sound complicated

thanks Grimber and TKN.I got it with your help.
