Making my own pattern and graphic

how do I make my own pattern from a picture? I want to do a Strawberry shortcake afghan from a picture of this graphic, what do I do to make it a knitting or crochet pattern?

You can try using this program.

If for some reason that doesn’t work, you can google knitter’s graph paper and print out graph paper and draw your pattern on it.

If you have a picture already you could use this program

Here’s another I found already made (from a site Ingrid had found), scroll down to strawberry.htm
