Try turning the paper about 30 to 40 degrees to the left ( if you
are right handed) or don’t turn the paper and draw them off set.
Get a picture of size in your mind and draw, draw, draw. Practice,
practice, practice. Draw as quickly as possible, don’t try to get each
one perfect. It will take time. As you get better at drawing you can
slow down, perhaps draw a very light quick drawing and then perfect it
with a heavier drawing.
Orientate the paper to get the required angle for the ellipse.
Customers can be very impressed if you can draw confidently in front
of them, Then say you will do them a proper drawing over night.
Get a few different rings or images and copy them, starting as
quickly as possible. The thing about drawing is: don’t get your
nickers in a twist’, relax, relax, relax. Practice in front of a
friend, talking all the time about the ring, stone, gold, whatever is
pertinent. I do drawings at 2 to 3 times life size,.05 lead,
templates, rubber. Scan on to Photoshop then clean up page with
rubber, reduce to size, save to letter headed template. Print By the
way there is nothing wrong with using different templates
eventually. I now do most of my drawing on Illustrator and Photoshop
now. Hope this of some help.
