7 months in and my strumming is starting to get consistent.
Still erratic using fingers.
I was using a 0.5 pick.
changed to a very flexible 0.38 which was the thinnest I could see.
Made a huge difference and allowed me to progress.
Now I'm Ok with a 0.46 and my 0.5s
Ups are way harder to smooth out.
Go gentle and slow.
It's a very individual thing.
