The color range of 20mm center hole sequins is ever increasing.
These large, round sequins will give a different effect than a top hole paillette.
Attach them to fabric and garments with a small bead to anchor them.
Alternatively, intentionally use a contrasting thread color or metallic thread to add to the embellishment.
Sew on the sequin from the hole to the edge with a spoke effect for added texture and color.
