A toggle -- a narrow piece of wood or plastic attached to a garment, pushed through a loop to act as a fastener. 

The toggles are grouped and described clockwise from top left:

1. Rolled paper, printed on the white cartridge paper, or painted black and a range of threads or fine   beading wire wound on.  The ends are wound with a narrow strip of paper, again painted black as are the ends.

2. Elongated triangles of printed paper rolled to make a  rounded shape rather than the cylinders above.  Both groups one and two could be attached by threading a strip of fabric through the bead.

3. Long strips of fabric (dyed cotton and net) bound with thread and then coiled.  The smaller toggle is firm to the touch and the addition of a sequin or button allows it to be attached to an item.  The net toggle is more of a rosette, though attractive not really practical as a fastening.

4. Padded white muslin beaded with tiny matte grey beads.  A rounded scrunched piece of black muslin fastened with crosses of thick linen thread.

5, More paper cylinders wrapped in threads, felt embroidered with fine lines and trimmed with tiny sequins or sari waste wrapped with fine beading wire, creating smooth and textured surfaces.
