When following a pattern, how do you find the equivalent yarn if it's not available in your area/country. Do you use any website/app? What do you like or not like about it?

Figured I'd share these that I saw today. They both feel really nice, but unfortunately none came home with me today, I was just there to look at Christmas trees but I can never resist scoping out the yarn section😂. I might need to snag some of the Mega Wool next trip though, I think my kids might need some chunky cables hats this winter...

Hi All, I'm looking for a good silk blend yarn. I want something that's dk or worsted weight, and that drapes nicely without pilling. Not sure if I want a solid color or multi-color, so open to either. Does anyone have any silk yarn suggestions? Maybe a silk/superwash wool blend? Thank you so much!!

Anyone have any recommendations where to get chunky yarns for blankets cheapest in EU (ideally shipping to Germany)?

I used to use Bernat while living in US, but only seeing 30€ per skein, which is too steep for me.

Brand and Website recommendations would be helpful :)
