Hard to believe, but there are just ten more main blocks to go. This block is the 159th, 49 pieces go into its construction. Total pieces so far: 3380.
I-13 has 2 versions. If you are using the book only, pay close attention to the picture of the original. The 4 focus fabric squares are considerably smaller in Jane's quilt compared to the drafted block illustration. I chose to go with Brenda's version, since I felt that hers would highlight my chosen fabric.
