Pattern – joining two atoms of the same colour
Cast on 4 sts, leaving a 20 cm tail
Knit i-cord for 16 rows

Thread each tail in turn onto a needle, pass through the cord of the same colour, cut so ends stay inside.
Work the knot inside the cord, and the stitches so they even out.
Thread each 20cm tail onto a needle and sew the bond onto the atom.
Pass remaining tail through atom, cut so ends stay inside.

Our prototypes were made with bog-standard acrylic wool, and the atoms stuffed with a slightly shredded half of a plastic charity collection bag. These are the sorts of materials that will be burnt in the Incinerator. But really, anything that is weatherproof will be suitable.
If you are new to knitting, some of the codes below may be a mystery. But the internet is full of
