Hi Wolfgang,
I like the concept and thinking, why cutoff an waste wood when you can adapt it to a larger piece by again using what could well have been waste.
It's well done, glue up is tidy and nicely finished.
We see this work done in many differing forms .. could a single timber worked better or the two used, but in thin alternating strips across the the bowl, should think from what we see you've the machining to do it as such.
Thank you for being innovative, should you not try it, you'd never know, nothing would be made if it weren't ever tried in the first place.
Cheers David
