This is now available as a free downloadable and detailed round by round pattern.

It is designed as a bag for Dungeons and Dragons dice that will transform into a tray.

The one pictured was made in Aran/Worsted weight cotton but DK/Light worsted cotton would also be suitable

The size can be easily altered by adding or subtracting rounds for the base and sides as long as you understand the way the base circle rounds are increasing.

It can be made in multiple colours or just one.
