This is a pattern for a mini cake. If made with the suggested yarn it will measure about 4 cm diametrically and 4cm height.

Gauge does not really apply, make sure to use a hook that produces a firm, non-see-through fabric.

You will obly need a few grams of 4 different colours of yarn and aditionally something like polyfill, a piece of thin cardboard or a piece of paper roll, and some beads.
