My 85 year old mom has a yo-yo 'quilt' her grandmother made. It is just as Hopetoquilt says - it goes over the blanket and the blanket shows through the holes between the yo-yo's. It is yo-yo's joined together. Mom's has groups of small multi-colored yo-yo's sewn together into squares - then there is a row of Kelly green around each of the 'squares'. The whole thing is on a diagonal and there are green yo-yo's all the way around. The diagonals are not filled in around the edges so it hangs in points. It is VERY elegant and VERY heavy and probably fragile at this point. ALL hand done. Mom only ever used it for special occasions so I've only seen it a few times.
