Setup for jewelry design

Since you prefer doing the manual sketches, but would like to catalog
them, you might consider getting a scanner. You can complete your
sketches, scan them to a PDF file & put them in an electronic album.
This would allow you to access them for future use. A small desktop
scanner can be purchased for less than $150-$200. You could use it
for scanning other documents, etc., as well. Just a thought.
