8 ply (DK) or 10 pl (worsted) are fine for this pattern.

How cute are these 2. This is my new favorite pattern. These mice are small and maybe even life size. The standing one is the size of the palm of my hand. Due to their size these mice are not recommended for children under 3.

The pattern includes 2 styles of ears. The bigger are knitted and the smaller are pieces of felt (instructions on how to cut are included). Either ear can go on either mouse - see second picture.

They are knitted on 2 needles. Use 8 ply (worsted) yarn. A great project for a beginner. The standing mouse is about 7cm (3”) to the top of his head and the lying mouse is about 6cm(2 1/2”) long, not including the tail.
