OK, this might sound like a super silly question, but I'm going to ask anyway.
How do you write with your fountain pens during hot weather?
What I mean is this: normally I write using arm movements with my arm resting and sliding on the desk surface, but when it starts to get hot and I wear short sleeve shirts, my arms are a little sweaty and tacky so they "stick" to the desk, therefore arm movements are precluded and I'm forced to use exclusively wrist movements, which makes my handwriting ugly and, most of all, it's uncomfortable. Not to talk about the fact that the paper sticks to your hand.
I tried with tablecloth: it's worse. I tried a sort of oversleeve and I can manage only for a while. I was thinking of dusting myself with talcum powder...
So, other than the obvious solution of wearing a long sleeve shirt (and suffer the consequences), do you have any other method of dealing with this issue?
