I would sew them together on point and then add a couple of triangles to "square" up the quilt, add a lovely lime green or purple sashing and then bind in either lime green or purple, depending on what you use for the sashing. I really would starch the blocks before ironing and squaring and make sure you measure them and find the smallest one first then cut all to the same size.
i am a new quilter and just found starch and sizing and love them to death. makes quilting soooo much easier. hope this helps.
