Hey Jennifer, what a cute pattern! It appears that you will cast on 8 stitches with one length of the main color yarn and then leave these stitches on the needle but not actually work on them until the section labeled Left Bottom.
So if you look at the chart, you will cast on Left Bottom, then cast on Right Bottom with a different piece of yarn and work Right Bottom for 3 rows, then pick back up with those first stitches you cast on for Left Bottom and work 3 rows, then join Left and Right Bottom together to make those little bumps at the flower end of the apple (you know, where the apple tastes the sweetest...yum!).
I hope this helps you understand what the pattern is saying.
Post any other questions you might have and someone here will help you...and be sure to post a picture of your finished apple!
