Are you talking about an entire quilt or just individual blocks to be used later? The back flannel back tablecloth works really well for quilt tops. It can be hung on wall (I use pant hangers) and taken down and rolled up to take to quilt meetings or when not needed. It can also be laid on bed for block placement and then rolled up for storage or to take to sewing room. For only blocks cut about 12" peices from table cloths and put them in unused pizza boxes. They will lay flat and boxes can be marked and stacked for easy storage. No pinning needed since the flannel backing makes blocks cling like magic! Also- I was taught when placing blocks to either lay them flat on bed if making bed quilt or hang them if making wall hanging. Each method give a different visual.. Good luck!!!!!!!!
