The bag in the picture is knitted using Tall Yarns Merino/Bamboo Sock yarn but any sock yarn or 4-ply can be used provided the gauge is not too dis-similar. The bag was knitted on 3.25mm needles, which sounds big but when knitting Fair Isle, it is advisable to choose slightly thicker needles to ensure the finished result isn't too tight.

About the clock
The picture shows a simple Ikea clock called “Redo” but the cover can just as easily be made to cover a different clock. Redo is a metal clock with a slight dome shape to its face and the hands run with plenty of clearance from the face so you don’t run the risk of getting them caught in the knitting.
The diameter of the clock is 28 cm (11 in) and it has one of these super-easy mechanisms that allow you to take off the hands simply by gently pulling them up and off the centre of the dial. Once you’ve knitted the cover, you simply remove the hands, slip the cover on and replace the hands. It really is as easy as that. If you’re using a different clock from the Redo, the key things to look out for when assessing its suitability are the clearance of the hands from the clock face and whether the hands can be removed to slip the cover in position.
