Hi,Although both Rosette and I made this type of design at Caithness, I would say this is probably one of hers. Two reasons make me think this...
1- The signature on the base is not consistent with my weights.
2- The buds do not have stems, not a thing I normally do.
The weight was likely made for the Scottish Glass Society Exhibition, but not necessarily for Rosette herself. We both quite often were asked to supply some flowers for the other workers in the glass house if they fancied trying something different for the Exhibition.
Hope this helps
Allan
