I wanted to examine samples of moss collected in the local area around the gallery where I have been working amazingly some were 150 years old. I was experimenting with time-lapse films of rehydrating small samples but need better magnification. Moss is stored in these paper envelopes, and if someone has worked with a sample (and rehydrated it) it is dried and returned to the envelope in a smaller paper wrap. I added a couple of my own to the collection, I like to think someone might stumble across these in a hundred years time! See more about the Gallery Oldham Bryophytes project here…
