Like a brush so much that you want to use it again and again? Then add it to your brush palette. To do so:

1. In a new document, create the new brush (or grab one from this forum).

2. Apply the brush to a line.

3. Save the document to the brushes folder.

brushes is a sub-folder within the templates folder. This folder is located in the same directory as your xara.exe

Don't have a clue what I'm talking about? Then check out Creating new default brushes in the Xara X Help files.
