It's already time for
christmas crafting so here 's one from my sister. She used old cds /dvds, glue and knitting left overs.
She glued two cds together so that she had two shiny surfaces and then she wrapped wool in two or three colors around the cds not covering them totally so that the shining shows through the gaps.
And here's another idea, you make a coil with wool in the center of the cd which you secure with glue, and also make a circle with wool on the perimeter of the cd using glue again.
They're simple and beautiful and most importantly you recycle some useless objects.
