I hsvent used a artline but I do own a couple of uni's, and im impressed with them .. Uni

 

My friend makes hats, he taught me how. Since the paint will bleed through and look like shit, paint the part where you're going to write with acrylic paint. Once it tries, its harder and easier to write and since it has a base it won't bleed through. I usually use white. It will be feel kinda hard though but I guess its worth it since it still looks nice =]

 

yeah i just did that for a friend who had some unis their good
