Yep, Rosie, I think you mix up something. "Metsä" really is the topic item of this thread. Doesn't the pattern look like "forest" like with branches bending in the wind?
Also this design is documented in a publication of the Finnish Glass Museum.
I know what model you mean with "cactus" as it has been discussed in some old thread and it most certainly was made by LasiSepät and whynot most probably was also designed by Pertti Kallioinen as he did a lot of designs for them.
I so far haven't just found any proof for that myself, nor the name of the design. Only items with LasiSepät sticker.
