Humankind, lilliputians and zippers

Two of the new minis I am making at the last week are done, they are 5.5"-6" (13-15cm).
The girl come with her tiny dog, and the boy carries his bicycle with him.
I made this bicycle from old zipper I folded and sew with blanket stitch. I tried to make them with wire, but it was difficult to work with and became thick considering that I wanted to cover it with textile. Then the zipper popped out as if people were using zippers to create tiny bicycles for tiny dolls for ages.
They are both listed at my store.
