… and just above the clouds.
Nothing too exciting 
Looks like great fun :)
Happened to me on a trip from Cologne to Prague, too. Cloud tops were at FL097 for about an hour, with class C starting at FL100. By the way, the ATC didn’t particularly like it and wanted me to fly at FL095 or below for proper separation. I wonder if this interpretation varies from country to country.
Hi Peter, may I ask what you did up there….. looks like flying around clouds ;-) but what was the intention?

Just messing about above the clouds
My son did this a few years ago
though I now think that soundtrack is a bit… corny 
If CAS starts at FL100 than the FL100 altitude belongs to the airspace below. In the UK I noticed that ATC does not like you to fly on the AP at FL100, but this is the way it is.

You should have requested to fly higher. The only downside is you need oxygen around Frankfurt as you need FL140 min to pass through that area.

I beg to differ. It says airspace C starts at FL100, at means that FL100 is already controlled airspace..
ICAO says that the boundary is classified as the less restrictive of the two airspaces.
The UK ignores this.
But, yes, mathematically you are right
