Swarovski Skills Camp, or men and their toys

10,000 Birds

The indoor workshop started with a Covid self-testing (where everyone was negative), followed by lectures on the Swarovski company, its ethos and products. The next day we had an outdoor workshop and a chance to test the toys. In comparison with ELs, EL 10s and NL 12s have the same field of view, as well as EL 8s and NL 10s.
