Would thick key bushing cloth work ? (I have a whole roll of that - used in 
various places for player work)

If you're going to use a strip mute, Schaff actually sells that. (page 36), in .165", .135" and .115" thickness, 50" long, and tapering from 3/4" to 1/2" wide. Measure your keybusing cloth and see how close that is. Or, look at some of the other felts you've got, and see which works best for you. 

For the midsection, you need to push the strip between the strings and give it enough of a loop to allow the middle string to vibrate. For the upper section, put the temperament strip on top of the dampers, and when you've got them all done, pull the dampers away with your fingers, and push the strip between the strings and the damper felts. Be careful that you don't damage the damper felts. On some pianos, the dampers don't want to come away from the string very much, so put your business card between the string and the damper, and the temperament strips will go down very easy. When you tune this section, the strings will vibrate a little, as if you've got the damper pedal on, but not enough to where it interferes with the tuning. 

But I stopped using a temperament strip about 10 years ago. I found using rubber mutes, even for a pitch raise, is much faster and easier. Since you're already doing that, don't change your method.  For the upper treble, I use a split mute, part 204 on page 36.

Thanks, this is all great advice.

Now - what are the tricks to strip mute ?

When I first started, I tried to strip mute and could never get enough space in 
the loops and the felt seemed too thick.

Also, since most of mine are uprights, it seems the traditional strip mute is 
too wide for the upper notes (either the 
dampers are in the way or the hammers are blocks)

There must be a special technique for getting the right size loop - and - 
getting the right size mute felt so the above 
does not happen.
