Ana, thank you for the link to the tutorial! :)

If mason jars are not the main attraction to this spice rack, they sell small magnetized spice jars to hang on magnetic wall boards (i bought mine on Amazon) I hang mine on side of fridge without spices, but could be adapted to a wood board with metal squares or strips and then perhaps a few mason jars or just traditional sized spice jars with a little water to keep some sprigs of herbs at a time?
