Life drawing is called “kroki” in Swedish (from the French “croquis”, which means “sketch”). “Öppen kroki” (“open life drawing”) is not instructor-led - you just turn up and draw.
You can book life drawing on the Folkuniversitet website. The poses are 2 - 10 minutes long, and the instructor does give tips and advice as you draw.
Lindholmens Konstskola host open life drawing on (most*) Mondays between 17:30 - 20:00.
*Search for dates next to the word “uppehåll” (“break” or “pause”) on their website to see a list of excluded dates (no life drawing).
KV Konstskola list their life drawing sessions as events on their Facebook page.
