You don't need all those items! Nature provides everything you need,depending on the seasons of the year.Winter flowers, snowdrops for instance.Spring flowers and buds.Summer blooms,roses are good.Autumn nuts, acorns,perhaps an apple. And don't forget bread all year round! Bread has always been important on the altar, every since Mankind began pounding grass seeds into flour!
The chalice and dagger (Athame) are for fertility rites.They come much later in life.
