Sorry to interrupt you and popman, but I have this odd problem that I couldn't solve using the OP. I have this cylinder that I would like to make a cord, but whenever I select Cloth Mode the mesh disappears. I checked to see if it was hidden and I also checked to see if it was in a different layer, but it was't. Also, when I removed the modifier I could see it again.
If it makes a difference it is pinned at one point.
