Berry bush orientation - by jove she's got it.
I finally cracked it! I got my other half to buy me a stylus for Christmas, so now I can see which way the thing is oriented when I drag it to the farm, and if it's wrong I can just let go and try again. Better than trying to peer under my finger or guessing where it's gone and whether it was my aim that was wrong or the orientation. Also a lot better for my blood pressure and the future integrity of my phone and my windows.
The stylus: the way forward.
(In actual fact he got me a packet of them - all different colours. They're on a little string that plugs into the headphone socket - so cute.)
