Have a look at all posted ready-made lamps...
Idea: Michèle Hofmann, München
Pendant made out of old plastic straps used for sealing packages, opt. glue, cable, socket E27, bulb
Recycling lamp, plastic cloud and oversized ball of "wool"
Fasten plastic straps into each other with knots, merge and mix until it is a ball. The ends of the straps may be glued together. Put the "cloud" around the socket with bulb and cable.
