Good luck with this Mick!
I hope that some Mail gets through to you.
Here in the South of France, one art exhibition I was in had to close after 2 days. 2 of the exhibitions I had organised for the summer have been cancelled. And I will have to cancel 2 Mail Art exhibitions -- one in the South of France, the other in the North of Holland -- as the venues will be closed. I'll be moving them on-line later as I have already collected lots of material for them.
I like doing mail art with digital images now. It really makes it fast and easy to post in my blog or here. All of the scanning and image fine tuning takes up too much time. It is different but still very enjoyable for me.
My best to you,
i will be in sending my booklet in the mail art about corona virus
thanks for posting at your blog
