Yesterday we went to the beadshop near where we live. We bought lots of things to make decorations for my hearing aids. My daddy wanted to make something to go on the tubes and he made these:
If you want to make something similar this is what you need: beads, wire and small pliers (and a stick or something the same thickness as your tube. We used a crochet stick).
You take a piece of wire, you thread it through the bead,
you twist the wire round itself several times,
then you add a new bead and start again.
my daddy put three beads in total. and when you have finished you wind the wire and clip off the end and tuck in the ends to make sure the are not spiky.
And this is what they look like.
