4" squares make a great OHIO STAR!
Combine 3 rows 2 alike to make just one block.
Look for a tutorial for scrappy ones.
Use a whole 4" s for the center, and using 2 squares, one scrappy - one plain, sewed and cut into a half square triangle for the points.( you will have little triangles cut off and left over)
Combine scrappy with a plain color that also will be your background color. You can alternate the scrappy stars with plain blocks - or scatter them.
