Cloth Physics hung on pole? I am trying to render a physics cloth of a flag. But I don't want to pin it to two points/an edge... I  want it to be wrapped around the pole. In reference to the image I have uploaded: The fabric is to be folded over near one side and stitched to itself about 2" in along the edge and one top edge. This would allow a dowel to fit into the "sleeve". How can I do this in blender so that I can render it on a pole? I tried to but it doesn't work properly.

I made the dowel an AddPassive in Rigid Body Tools and the flag a Cloth in Physics. They don't intersect.

I also would like to know how I can better make the sleeve rather than making a tube.

Thanks!
I don't think subdivision and self-collision matters much, even the model size (just don't make them extremely tiny). In fact, subdivision generates even worse artifacts in some cases.

For the "exploding" issue, what matters much is the Distance parameter in Cloth Collision panel for cloth object, and the Outer parameter in Collision panel for the collision object. When the initial gap between the two objects are relatively small, you need to tweak these two parameters specifically so that they will not become "procedually intersecting" before running simulation.

Of course, subdivision will lead to much better result, as long as key parameters like above can be taken good care of. But it doesn't mean other things are trivial. For example, don't forget to apply Scale for object when doing so.
