These designs were made with smaller HST's which will result in many more variations, using some pretty Moda fat quarters. The first few are for a rectangular table runner (borders would be added):
Same squares, arranged for a square table topper:The HST's could also be made even larger and a lap quilt or even a bed quilt made from them :-). Simply make lots and lots of these units and keep designing.
