No, it's not the batting.

edit: If you get overwhelmed with it, consider using alternating plain blocks or sashing to make it the size you want.
Hello--I should have said quilt assembly not block assembly when describing the steps. The first part of the directions describe the applique process onto fabric 1. The interlining step is a different step. Also, there were only 8 out of the 28 blocks that were finished with regards to the embroidery of the cat details. So I am finishing all the embroidery work. That was why I was excited to find the pattern to see how it compared to the original person making it.
