With Valentine's Day right around the corner, I wanted to make this pattern available here in my Ravelry pattern store - the Celtic Heart Knot Pin.
We made this project on our Craftours/Annie's Crochet Tour of Ireland last summer (June 2016) during one of the workshops I taught. It uses a very small amount of yarn and can be made quickly. Several of the participants finished their pins and wore them proudly around Ireland.
To complete the heart you will need a small amount of coordinating or contrasting felt that is glued or sewn to the back of the heart. You may choose to attach a pin backing or include a key ring as shown in the photo above.
As you can see there are many edging options included in this pattern. A diagram of the Celtic Knot is also included.
Happy Valentine's Day!
