What am I doing wrong?

What am I doing wrong? - student project

Good Morning, Anne!  I love in your write up that you start with your age!  I'm 75 and trying so hard to learn surface pattern making in Illustrator.  I've followed your instructions over and over and no matter how good I get at making the beginning of a pattern, this is what happens after I drag and drop to my swatches and check the pattern.  They all turn out like this.  Please.  What am I doing wrong?

Thanks,

Mary
