I have been getting on with for-Christmas orders from customers who came to my stall at Christmas markets who needed different sized rings and bangles.
As I make all my rings and bangles myself, I can make any of my recent pieces in different sizes so long as I have materials in stock. Admittedly, no stones or sea glass will be identical, but there is a good chance that I have similar ones.
I am still working and if you are local, I can still make rings and bangles in time for Christmas. DO get in touch.
