I made this necklace for my niece for her 21st birthday recently (well tecnnically I only made the Poke ball)...
starting with these
and unsuccessfully painting them with model paint which failed and remained sticky forever, then resorting to a good old Sharpie.
The rest of the beads I incorporated into a friendship bracelet made on a circular 'loom' made from a piece of cereal packet.
Every few centimetres I undid one of the strands of wool from the loom, threaded a bead on it and pushed it through the hole in the centre of the cardboard loom, replaced the strand and carried on weaving the bracelet.
