I'm thinking i have understood the question here to be simply where do you start making a pattern??
this has been discussed before but i couldn't find it
Start by doing a Google image search for the item you want lets say "teddy bear"
find what you want or take a picture of what you want.
do your best to re-size it to the size you want to carve and print it out. quality dont matter as your going for outside shape mainly..
method 1
you may have to improvise to make the side view, so drawing horizontal reference lines across the printed page will aid in keeping features aligned in front and side view, or print it out on graph paper...
use your knowledge, knowing the nose is most forward on the head and ears will be some what to the back of the center of the head then the back of the head will define the rear vertical limit of the side view, find out if the nose or pot belly is the other vertical limit to the front of the side view,,
try to keep some realistic scale then continue drawing vertical lines
align the top of the head in both views Along with the tip of the nose, eyes & chin arms paws, fork in the legs knees and feet from view to view..etc..
use the reference lines and sketch the side view until your satisfied with the shapes, then fold in a straight line between the front and side views and attach the fold over a corner edge of a block of wood you intend to carve,
tape it down securely with clear package tape and using a band saw, scroll saw, or coping saw to follow one view all the way around the pattern.
re attach all scraps to make as solid of block as possible then secure with packaging tape again..
roll the block to the uncut view and cut out, when finished you will have a rough cut out..
method 2
use your 2 view pattern, and trace the outside lines directly on your stock with a pencil, then with knives and chisels remove all the stock outside the pattern lines,,,
continually keep redrawing the pattern or highlights while removing stock so you dont forget, like the stock in front of the eye has to be removed, but you need to leave stock for the nose, mouth mound etc.
try the pattern attached
