The news is: the brooch has been approved for casting and I should have it back by the end of the week. I need to meet the deadline of 4 April which should be achievable - all going well.
I have just finished another large bridal order and this was collected today. I will begin my next order tomorrow as I need to be up to date before the 'return of the brooch'.
It's kind of late - 1.46 am - time for bed.
