I would string little beads on threads to make garland, use buttons to for decorations or other little cute charms.
You could always embroider little things on them too.
I was going to say embroidery too!Maybe even braid some thin ribbon and attach for garland.
How about little circles for Christmas balls from your stash and then use fabric glue on top with sprinkles??? Julierose
They are so cute I might just leave them alone!
