Making my own patterns

by Heather Gray
(Stirling, Canada)

I would like to be able to design my own patterns, particularly from photographs as this is another hobby I enjoy.

Is there a software program that will convert a photograph into a line drawing?

Also, I have found an interesting stain glass pattern software program that would allow me to create my own patterns but I am not sure where I should be putting the lines to ensure strong construction.

Can you recommend a reading source that could help me with this issue?

I am not in a large urban centre and obtaining desirable patterns is my biggest challenge. I enjoy detailed, although not necessarily large, stain glass pieces and would most like to try to create my own.

I look forward to hearing your reply! And thank you!
