How about alternating the variable star block with another block that we have learned to make. The 9 Patch. I quite like the effect of this one. The green triangles on the star block create a secondary Sisters choice pattern when placed next to the 9 Patch
Also included below is the Pdf file of instructions for piecing the Variable Star
