This is to make your log cabin center block in the middle of the star.
Remember, match up opposites of your half square triangles right sides together and mark from corner to corner. Sew 1/4" away from the line on both sides and cut along pencil/pen line.
This will give you two of your meeting point squares for your alternate blocks.
If you would like to make this quilt on your own without joining the class, we still have patterns for sale in the store. The quilt is called Stitching Stars by Sandra Stradley.
