Herb wheel

[CLH13]

Hi folks!
OK, so I've built the raised beds and I've got some wood left over - anyone know how to build a herb wheel????
Maybe a herb wheel is a bit ambitious - would a square(ish) planter with a grid/dividers in it do the job? If so how big should I make each compartment?

Thanks in advance

A Plant Divider would do the job, but it depends if you want to be ambitious. If you want to make a large to medium square divider I'd make each compartment about 20 cm by 20 cm. If you want slightly bigger go for 30 cm by 30 cm.
