What are you doing with the seaweed?

from w
'Grandma, why are you picking up that seaweed?'
'Wait and see.'
'Grandma, are you going to cook it?'
'No, it looks like lumi but no.' (Lumi is a Fijian delicacy of cooked seaweed.)
'For medicine?'
'No.'
The seaweed was brought back from our sojourn at Barwon Heads estuary and I laid it out on a bench outside to dry out. Next morning I found it floating in a tank of water, The boys thought it belonged there! I took it out and then it rained. Anyway eventually I did some scanning of the seaweed to make pictures!
