St. Patrick’s Day is around the corner – and making art for holidays can be just for fun or perfect for a card to send good wishes to an Irish friend! Today’s project is easier than you might think it is – give it a try!

What’s a Celtic Trinity Knot anyway?

Celtic knots have a variety of stories associated with them – including Christian!

The three points of the knot are symbols like the divine trinity of Father, Son and Holy Spirit;  love, friendship, and strength; and so many more you’ll find listed all over the web. The interweaving lines, without beginning or end, symbolize eternity.

Tutorial: Celtic Trinity Knot

How easy is this?

I know some of you may think this looks hard. But I made it easy! There’s a PDF you can get for free HERE – and it has the basic math *SIMPLE MATH* and instructions.

First is making the “trefoil” – the three interwoven “leaves” of the design. If you can measure a SQUARE, then you can locate the three points on the outside of the circle and the center of it. Then let the compass do its work!

Interweave the lines

Make them look like they weave in and out by erasing either the vertical or horizontal lines from each section.  Just remember that each trefoil has a “left” and “right” side – once I kept that in my head it was something I could follow. (Don’t do all three leaves at once; focus on one so you don’t get lost.)

Embellish – or not!

Knots can be very basic, or extremely fancy! Google the knot and you’ll see many examples for inspiration. I decided on one simple leaf repeated three times. Placing your repeating object in a way that it starts/ends in a location you can easily find is helpful. Tracing paper can help too – trace that thing three times and lay it over the page to arrange them and see where you want to start/end.

Add color!

Not all Celtic Trinity Knots are green, but many are – I did see some lovely purple ones, rainbow ones – so basically you can do whatever you like! Mine’s in watercolor, with glazes of watercolor that helped me shift the color as I went.

Give it a try!

The free PDF is available to help you out! I’ll be posting a few more of these this week on social, so keep your eyes open for those in different mediums!
