As for the 62 blocks ,I would mount them like a dresden plate, with fusible . turn wrong side to wrong side of fusible an sew all around . trim in circle,make a slit in center , turn and. press to a block of muslin , white or tone on tone,then sew all around with invisible thread , then stitch of your choice.ie button hole or hem stitch.. then i would sash and cornerstone , and border. would be lovely jusy mho. cmaras
