From the pattern description:

> This cosy felted rug will warm you up
> on those chilly winter nights.
>
> The idea for this snug rug came about
> from one of Jennifer’s first knitting
> experimentations - a lovingly worked
> poncho that shrank down to a felted
> rectangle and has since been used as a
> throw, a blanket and a rug. She has
> always liked circular rugs and played
> with possible ways to make a circle
> inside a circle, yet construct the rug
> in pieces, as she didn’t relish the
> thought of carrying around the almost
> finished piece!

Tip from pattern:

> The Freedom Wool from Twilleys of
> Stamford felts very quickly and easily
> into a lovely, dense and firm fabric.
> Stormy blues with a grey tinge make
> this very easy, dramatic piece. No
> special techniques are used for this
> rug: it is worked in quarters with a
> selvedge to ease the making up at the
> end. Increases are worked every
> fourth row evenly along the needle.
