I agree, its amazing and generous of people who have purchased patterns to share them here with the rest of us. I especially like this site when I don't want to support a certain creator, but I still want to use one of their patterns.
Hi, welcome to the forum! I totally agree, I can't always afford all the patterns and this way it's easier :) The other users' suggestions are also really valuable to get better at crafting.
Hope you can find what you're looking for! :)
A small tip; if you can - do invest in quality yarn, wool, fabric and stuff. Because this can make or break a project.
(and I know from my own work -amigurumi's- that low quality can get you more work)
