The working
Draw an equilateral triangle lightly in pencil. On each side, draw an arc bulging outward so the three arcs form three pointed loops, then erase the triangle.
Ink the knot so that the line goes over, under, over at each crossing, the way Insular artists drew their interlace.
Add a circle woven through the loops if you want the common modern form, read as unity or eternity.
Name the three things you want bound together and protected: for Christians, Father, Son and Holy Spirit; for others, perhaps body, mind and spirit, or three people in a family.
Keep the drawing over a door or in a wallet, or wear a triquetra pendant as a reminder.
If you knot one in thread, tie it as one continuous cord and hang it in the home.
Take care: No safety concerns beyond the usual care with any thread or small pendant around young children.
Versions across time and place
i
Book of Kells interlace
Irish monastic art · c. 800 CE
The triquetra appears among the interlaced ornament of Insular manuscripts like the Book of Kells, now at Trinity College Dublin. There it is decorative; scholars caution that we do not know what meaning, if any, the scribes attached to it.

Stone crosses and the Hexham frithstool
Insular Christian stonework · 7th to 10th century
Triquetras are carved on high crosses and grave slabs and on the stone frithstool, a sanctuary seat, at Hexham Abbey in Northumberland.

Modern Pagan and pop-culture use
Celtic revival, Wicca, television · 19th century to present
The Celtic revival popularized the knot as a Trinity symbol. In the 1990s the television series Charmed put it on the cover of the sisters' Book of Shadows, and many Pagans now read it as the triple goddess or as threefold protection.

History
Three-part interlaced designs turn up widely, from Anatolian and Persian pottery of the 4th century BCE to Germanic metalwork with the related valknut. The classic triquetra flourished in Insular art of Ireland and Britain from around the 7th century: metalwork, carved crosses and illuminated manuscripts including the Book of Kells, made around 800. The word triquetra is simply Latin for three-cornered.
Whether the early medieval artists meant it as the Holy Trinity is unknown, and specialists warn against reading too much into ornament. The Trinitarian reading became popular with the 19th-century Celtic revival, when Irish jewelry and church art used it as a Christian emblem. In the late 20th century it was adopted by Pagans and fans of Charmed, and it is now among the most popular Celtic designs for jewelry and tattoos.
