Never use the line tool for boarders. There is a much easier and better way to do it.
When you make a boarder do it at the end, it's the last thing to do even after the font.
Make a new layer and use Rectangle Tool and cover the whole sig. Then go to Edit and select Stroke. Then decide the color, and width and your boarder is done much faster that using the line tool.
Also from there, you can do tons of things to the boarder like adding a shadow, another stroke, etc. etc. Doing this gives you a shit load of more options and a major time saver.
Fonts are tricky, I learned a lot from reading Tutorials about fonts.
Wow I never thought to do the border that way, that seems a lot easier. Thanks
