Herb Pouches/Charms - Dried (fresh can dry out in the pouch to a bitter smell, or even mould in some cases)
Altar Decorations - Fresh and Dried (either together or separate)
Incense - Dried (fresh can burn to a bitter scent with certain herbs and will not burn as well because of moisture in the plant)
Offerings - Fresh and Dried (either together or separate)
Rolling Candles - Dried or Fresh if using thyme or a similar herb (you need much less though)
Wish/Spell Boxes - Dried (with the lid being closed fresh tends to blacken and dry out chalky because of lack of air circulating or even mould)
Herb Mixes - Dried (especially if you will not be using it all but storing some) or Fresh for immediate use (especially good for altars, sprinkling around house)
Oils - Dried will last the longest 3 to 6 months but will go off unlike oils made from essential oils. Fresh herbs can be used but their water content can cause them to go rancid.
These are just a few examples and guidelines but as with all good magic trust your instincts and go with what feels right for you.
