I know - not very seasonal! But I put some Christmas garlands together today, as I was going through a whole crateful of old bead necklaces I've had for years. They're the cheapy kind where the beads are glued to the string. I collected dozens of them from charity shops a few years ago so I could make a bead curtain for my back door, by fastening them end-to-end in long strands.
Having moved house several times since and never having used it again, I decided to get them all out and sort them. I sifted out all the red, green, gold and white ones, fastened them together and put them in my Christmas decs box.
Then I pulled out all the ones in my favourite colours, which I might wear myself (below). There are some which are the same colour as others, but a different shape or length - I'll decide which work for me by trial and error! The rest - still a carrier bag full - will go back to the charity shops... unless I think of some other creative use (or mischief...) for them.
