Nancy thought the Illinois Star was an easy block to make. I suppose it was easier to do by hand but I don't think it would be that easy by machine with the pattern pieces I assume she would have used based on her drawing.
I added a few lines to my Illinois Star pattern for a 6" block so I could paper piece it by making multiples of the same section like this-
Four of these sections are all that's needed to make the block! View my paper piecing tutorial here.
I could not find any examples of blocks or quilts using the Illinois Star quilt block. The block is however available in Electric Quilt's Blockbase program as as #2744. You can download my paper piecing pattern here.
