I would say this pattern is intermediate. I presumed that people have different level of knitting skills. This pattern is clear made even somebody is a beginner. It is includes step-by-step written descriptions on how to knit the Tea Cozy with a pocket, photos of process are added.
The video tutorial link on how to knit a sleeve is included.

The finished Tea Cosy will fit a 4-6 tea pot.

Yarn: you can use any of Aran (8 wpi) weight yarn like Wool-Ease Solids by Lion Brand.

Materials: a set of size 3 mm (2 1/2US) double point needles, one pair of size 3 mm (2 1/2US) circular needle, a cable needle, two small buttons.
