texture mapping

i''ve created my own sphere using tessellated polygons. I start with a isohedron, (20 triangles) and subdivide this to a appropiate depth to create a sphere. Now i want to put a texture map on this sphere but i''m having trouble, it appears to draw the texture map 8 times (imagine a sphere split into 8 equal chunks) i''m using glTexCoord3fv(v1) each time i draw a vertex on a triangle. any suggestions?
