Put two two and a half inch squares together, face to face and use them for leaders and enders. Then press, run them through again and make four patches, press and sew two four patches together and then sew the two half blocks together and you will make 8 patch blocks. I like to machine embroider some off white blocks and make kids quilts out of them. They are really sweet with baby faces, sunbonnet sues, or overall bill blocks. This makes sort of a "free" quilt while you are makeing something else when they are used for leaders and enders. Sometimes I get inspired and just sew a batch together.
