I found this pattern for a crochet cabled tea cosy online after much searching. I haven't done crochet cables before and really wanted to have a go, It was quite interesting to do and gives a really lovely effect. The yarn was some old Patons dk that I found in a charity shop recently.
Another favourite design of mine is the Buddha's Knot No Sew Teacosy - also a free pattern. It's really easy and that little i-cord knot on top just finishes it off nicely. When I found this amazing rainbow yarn in Hobbycraft I knew it had to become one of these. I am keen to get hold of some more of this. It makes for a very cheerful little cosy. Enough to brighten up the dullest of mornings!
I also made up this cosy in some of the Yarnfair striped yarn.
Lastly today, this granny square teacosy is fairly cute but I hated all the sewing up. I think I would also prefer it more random colours for a scrappy look.
