New To Blindfold Chess Please Help

I just started getting back into Blindfold training 2 weeks ago and am starting to be able to visualize some fragments of the chess board mainly the 4 central squares and the a1-h8 diagonal and the h1-a8 diagonal.  Any advice on how to improve on my Blindfold chess and Visualization?

Just as a random beginner, should I learn blind fold chess?

I would offer advice, but I am not that good at blindfold either.

Just tell me something you learned that you think I should know or that I might not know.  You are probably better than me

Probably not yet, but you should start to learn the coordinates for both black and white so you can understand chess notation if you don't already.  I'll just say there are more important things for you to do and learn but Blindfold chess won't hurt you, and it does actually help your visualization and calculation in regular chess

Pattern recognition could help

Yes indeed, this might sound pointless but one suggestion that worked for me that I came up with was to examine the blank chessboard and recognize and appreciate all of its geometrical patterns

Why does it sound like you're speaking from experience😂😂😂

I practiced this with a coach; I'd look at a blank board, and he'd verbally tell me to place a set number of white pieces and black pieces on the board; often endgames or tactical positions, and play on from there. He'd play against me, just verbally saying the notation and I'd reply. There'd be no pieces though, all just verbal and using the board for grid reference.

Also drill the chess.com visualization trainer. It's useful.
I still struggle with visualising a firm grid in my head. Especially after about 10-15 moves - after that, I start to forget about enemy pieces blocking my moves.
