Thanks for your question. Sure it is okay to ask here, this community needs more active members.
As for your question: I also haven’t got a clue about worsted weight yarn as I am from Europe myself. So what I do is look for a similar gauge and buy whatever I like. Works out fine most of the time.
Yarn is expensive in large amounts and wool even more so. So 180€ seems normal-ish for this amount of wool. I am sure you could do cheaper than that but not too much. I would consider making the cardigan from cotton yarn, which is still gonna be expensive but probably less than 180€
Hope I could help!
Der Brachiosaurus-pterodactylus-teller?
I am not since I watched the latest season of rick and morty. Ahhh
The one where O’Neill steals alien stuff to go undercover with a rogue NID group to catch them in the act. O’Neill meets a Mr. Newman via a goauld television communication device. As he is not happy to see him, O’Neill greets him with a “hello Newman” that sounds very much like the way jerry Seinfeld adresses his neighbor.
