Hel is the Queen of Helheim, Lady of the Dead, sister of Fenrir and
Jörmungand, and daughter of Loki. These are ways I personally honor Hel and my personal associations with offerings. If you have something negative to say keep it to yourself, these are personal and work for me.
When the earth is quiet and the grounds are covered in snow take a hike in solitude for her.
Volunteer to help those who are recently bereaved.
Use bones or the crystals onyx, petrified wood, tourmalated quartz, smokey quartz, obsidian, and jet.
Cook meals for the homeless, at the soup kitchen, or someone in need who society won’t help.
Decorate your home in photos of passed loved ones, bones, dried herbs/flowers, and wolves/ravens.
Leave a drop of your blood in freshly fallen snow as an offering(this also works for Skadi).
Use snow water and graveyard dirt in your practice or altar.
Listen to music that reminds you of her. I’ve noticed she likes cello and piano pieces quite a lot.
Practice crystal ball scrying.
Leave offerings of food(that are also safe for animals) out to rot in the wilderness like apples, meat, cabbage, etc.
Keep a window open at night(granted it’s safe).
Leave offerings or saying devotional prayers under the new/dark moon.
Light candles or incense of mulberry, wine, apple, musk, rose, and winter themed scents.
Make offerings to your ancestors and honor the good that they’ve done but don’t deny the wrong they’ve done, learn from it.
Have a glass of apple cider, apple tea, or spiced teas like chai in honor of her.
If you feel anxious, depressed, or insecure give those feelings to her as an offering. Focus on healing after.
Use the runes Berkano, Isa, and Hagalaz in your altar or practice.
Remember that solitude can teach you many lessons about yourself.
