How do I convert a pine wall to a plastered or fully spackled wall?

[chlaras]

hello! I am renovating an old wooden house and really need tips and help on how to best create smooth walls from pine walls.

- it doesn't need to be perfect in appearance (i.e. it can have some texture, not necessarily completely smooth)

I am really a rookie so all help is gratefully received.

thank you so much!!

the first picture is from the house, the other three are inspiration pictures to clarify.

Clay plaster or plaster with lime mortar.

The method already used probably works again, a panel material + wallpaper or why not just paste gray rag paper and paint the wall?
