Below is a list of many places/ideas for you to put sigils. Sigils are probably one of the most simple, yet effective forms of magick, I use them all the time! If you’re lost for uses of them, I hope this helps!
Favourite Books- If there is a book you often read, you could put an important sigil on the back of the cover, so when you open the book you will see it. You could also use a protection sigil for the book. (Maybe on your grimoire?)
Mirrors- You can use whiteboard markers to put sigils in the corners of your mirror, so when you get ready in the morning, or whenever you’re near the mirror, you see the sigil. This is perfect for self-confidence or self-love sigils.
Sticky notes or cards- Draw a small sigil on small square of paper so you can fit it into a locket and wear it around your neck. This would be great for protection sigils, attraction sigils etc
Stationery- This one was asked in my ask box, whether you can carve sigils into pencils etc, and the answer is yes! You can put sigils on your stationery, or in your pencil case etc to encourage positive feedback in exams, concentration and happy studying
On calendars- If there is an important date coming up on the calendar, put a sigil on it, attracting positive vibes towards it!
Windows- Use a whiteboard marker and put sigils in the corner of the window to make sure you’re always looking at a happy sight. (I don’t know if many people would go to the effort to do this, but if you want, go for it!)
Sewn to clothes- You could embroider a sigil on the back side of a coat or piece of clothing to protect you. (choose one of those double fabrics, the ones that won’t go through to the other side)
On your body- If you can find non-toxic markers that you can use to draw on your skin, you could draw sigils on your upper thigh, or places where they are not so noticeable. This is good for body confidence sigils etc
Sentimental items- Draw a sigil on a sticky note and stick it to items of sentimental value to protect them, or maybe attract certain things concerned with the item
Bottom of your shoes- You could place sigils on the bottom of your shoes for protection when walking home.
Garden- You could make little ornaments for your garden with sigils on them to promote happy growing
Hairbrush- you could put a sigil on the handle of your hairbrush, to promote hair growth
You just have to get creative with it!!
