Here's two sources for you Beatriz! Earrings are easy and fun to make! Be sure you buy higher quality wire for the parts that go through your ears. I am allergic to certain earring materials so I have to be careful about the earrings I make and buy. Have fun!
So many ideas here!

Here's a post from my site on making earrings with old soda cans: https://mermaidsden.com/blog/2014/08/02/aluminum-cans-and-jewelry-part-ii
There are a million videos online. Just Google for the kind you're interested in making. And most are super easy. You can also take classes at craft stores. I know that Joann's in my area gives them.
You can buy earring findings/backs on eBay or in craft shops etc. You can also buy books to help you or look online for a tutorial.......
If you have a picture of what you want to make that will help us provide more specific advice.
