Crochet triangle shawl without pattern

I saw a great triangle crochet shawl

and i would like to make something like that. As im a beginer in crochet and i don’t have pattern, i would like to hear if anybody has some ideas how to crochet this shawl, is it combination of single, double crochet stitch, or is it bit a complicated what kind of wool i should use…
Thank you!!!

It’s done in very thick yarn with a huge hook and seems to be double crochet. I’m sure you could find a pattern for a regular triangle shawl and just use the heavier yarn and hook.

Thank you very much!!!
