It's like doing hair in a french plait.
Tie three large bulbs together and lay them in front of you as pictured. I find it easier when the stalks are still green but they must have been dried in the sun for at least 3 or 4 days so the plait doesn't rot.Next find a bulb which sort of snugly fits in the middle, lay it's stalk on the middle stalk.Snuggle the next bulb in on the left, you will plait it's stalk and the left stalk over the middle ones. They then become the left stalks and the previous left ones are now in the middle.Snuggle one in on the right and cross the two right stalks over the middle ones as before.Find another one to snuggle in the middle and repeat the process to make the plait as long as you like. I use smaller and smaller bulbs as I move up.
When you have added as many garlic as you want plait the stalks and tie the top. It is now ready to hang and use. Many people plait their garlic, feel free to link to this post. I would hope that any learning or perfecting their technique from me would respect that I sell my original garlic plaits locally (motueka and surrounds) to help provide for my family.
