From Square To Eternity
This is one of our earliest afghans - and still one of my favourites. I particularly like it because, apart from the very smallest squares in the centres, the number of stitches is always decreasing and so it seems to go very quickly.
You can use any yarn and needles of your choice and the pieces are guaranteed to fit together. This is a very easy project for all levels of knitters. It is also very portable as it is knitted in various sizes of squares which are stitched together at the end.
The PDF includes a page where you can try out your own choice of colours.
