You could, also, applique them around the outside border of a quilt. You could just embroider a simple winding line of green around the edge and then applique the single hexagons here and there next to the green line as "flowers" with maybe a button for a center.
Or use them for a child's quilt and embroider "dot" eyes and a "v" or"u" mouth on each one and make them into funny animal characters. Good Luck!!!
