How do I learn country lettering?

Hi. There are lots of great videos and posts now about learning how to create script and fancy lettering. If you don't feel comfortable spacing and making letters, you can also use one of these super easy methods. I use them all of the time when I transfer letter to signs, furniture, chalkboards etc... Hope it helps! https://recreateddesigns.myshopify.com/pages/how-to-transfer

How about buying stencils?

Are you wanting to hand paint signs or something?

I use the website The Hungry JPEG and they have lots of free and cheap fonts. They happen to have a free font bundle this month. You just have to share it on your social media: facebook or twitter.

I think you might be referring to Brush lettering. There are tons of blogs, facebook groups and youtube channels that can teach this skill. If possible, start on an iPad with an apple pencil before you pick up a real brush pen. It's easier to undo mistakes on an iPad. Otherwise, have plenty of paper ready and know that it takes about 6 months before you get good.

Stenciling will help too
