Covering I-struts

[Vilhelm]

I had initially considered to cover the upper and lower parts of the I-struts with aluminium sheet, but now I think it will look much better with fabric covering.
But looking at them it seems to be difficult to get a nice transition of the fabric at the sharp angles where the round support tubes meets the streamline tube.
I am sure somebody here knows a good way to cover these struts,
