Cloth Collision Issue

For some reason I can’t get my cloth to stay hung to the torus. The torus is initially looped through the cloth.

That’s a job more appropriate for pinning than collision. The vertices of the part of the cloth that sits within the torus should probably be fully pinned. Those around the hole may not need full pinning but it should probably be fairly strong, around 0.50 or so. The rest can be unpinned. Sometimes a little graduated pinning weight from full to zero can help keep things looking more natural at the pinned portion.
