Then inspiration struck - these bags could become mini Santa hat bags with a pom pom and some felt. Add some wrapped chocolates and I would be sorted.
I removed the tag from inside the bag then used hot melt glue to attach the white pom pom to the top of the bag, above the drawstring.
Next I put a line of hot melt glue along the bottom of the bag and attached a piece of white felt which had been cut to size.
