Very nicely done Raimund. Is it renovation or recycling???? LOL
I have a small hook box consisting of eight 25x25 mm squares filled with gravel from the streams where the cased caddis imitations have been especially useful. Now I just build a cylindrical underbody and coat it with superglue. I then roll/dip it into the “right” colored gravel for the particular stream I want to fish. Of course, I can blend the gravels to get the best match so color variations are pretty much infinite.
Your way seems much easier!!!!
