I thought I would put some older things on today.
The one above - bright feathers trapped between plastic and fabric with hand stitched circles.
Below - painted bondadweb, the circles are sweet papers with their centres cut out. This could be a starting point to be developed with stitching etc
Below - painted paper, the foil centres are milk bottle tops [now you don't see those nowadays do you?], with sequins stitched around them. I used found chain [the type that looks like tiny little balls joined together] around the edge of the darker area.
Below - threads were wrapped around a thin metal frame and a central ring and then circles were stitched on the sewing machine. The threads were cut from the outer frame but not the the ring.
