I had lots of small pieces of fabric leftover from many projects that were one yard or less. I also had lots of boxes and shoeboxes. I made the boxes into pretty and stackable storage by covering them with the fabric leftovers.
Add a canning ring to Mason jars when using them open to hold flowers, etc. You still have the look of a lid, but it dresses up the rim. You could also use lace or ribbon to dress up the edge and give a finished look.
