Hi Mary,
I went online and looked up Dr. Suess pictures, used some books as well, I used thermal embroidery topper (plastic that you embroider over to keep the nap down on the fabric so the thread will be under, then you iron and it melts away) to trace what I wanted to embroider. I hooped the fabric, then just started sewing on a straight stich with a embroider foot (I have a Brother embroidery machine-but this is free hand embroidery). It is like coloring with thread.
