Hi Masik,
How amazing to see your post today as I have news for PG members. First of all, happy holidays season to everybody.
I just fixed yesterday that I am going to give lectures on "History of Clasps" in USA again !
Yes I will go the California next April.
I had so much fun in May in New Orleans and in June in New York giving lectures, that I wanted to go West Coast. And meet Sheri again
In 2018, the "Clasp Book Tour" will include Paris in March and London in October at the Society of Jewellery Historians.
And you might like to read the review written by their magazine "Jewellery History Today" in London,
