Making a Digital Signature
It's easy to make any shape into a 'Brush Preset' and to convert one's handwriting or signature into a 'Brush Preset' this is what you do.
Start with a new blank document.
Go to File > New Document.
Choose a suitable size brush and set the 'Hardness' to 100%, unless you prefer a soft edge appearance. Alternatively use the 'pencil' option from the Brush Tool icon on the Tool Bar as this will automatically provide a hard edge.
Make your signature. Note: This is very much easier with a graphic pen and tablet rather than using a mouse. However a mouse will work with a little practice.
Go to Edit > Define Brush Preset
Give the preset a name click 'OK' and that's it. You have a 'brush' (pencil) with the shape you need.
