These are ways I personally honor Freyja and my personal associations with offerings and her. If you have something negative to say keep it to yourself, these are personal and work for me.
Do not declaw her for being a goddess of love and beauty. Recognize her for the god of war that she is, Queen of the Valkyries, and god of the Vanir.
Decorate your home or altar with cats, honey combs, horns, or bones.
Practice self love in it’s totality, look at where you need to grow but recognize and appreciate your strengths.
Carry the crystals(or keep in your home): amber, rose quartz, gold, emerald, labradorite, and copper.
Dedicate a piece of jewelry to her in honor of her Brisingamen.
Drink floral teas like lavender, chamomile, rose, or jasmine with honey.
Use the runes
Fehu, Kaunaz, Jera, and Uruz in your craft or altar.
Take a bath in salts, roses, and lavender. Decorate accordingly!
Enchant your make up to make you feel beautiful, confident, and strong.
Learn self defense or kick boxing; or just do something to help you stay active and strong in her honor.
Light incense or candles of rose, honey, jasmine, amber, strawberry, dragon’s blood, or musk.
If you’re looking for a cat look at shelters and pounds first, rescue a little baby or donate to shelters/vets.
Pray to her for your loved ones in battles whether it’s oversees, a disease, or an abusive relationship.
Leave her offerings of mead, weed, wine, red velvet, roasted nuts, honey, pork, bread, or chocolate.
Watch movies/tv shows with strong female leads(preferably with none problematic actors) like Wonder Woman, How To Get Away With Murder, Mowana, Queen of Katwe, etc.
