Memory Bears that I know of (I know a gal that makes them) are made with shirts/blouses etc. of a loved one passed on. Made for the family members to remember them by. She made ones for her family when her mom passed the one she made for herself was out of 3 different tops that she loved on her mom. And no she won't give up the pattern.
I agree with the rest of the posts that you can change your pattern pieces to make the bear look like the one in the picture.
Just thought I'd add this.
