Leeks out of paper tape !
Three colors of papertape. The kind you use for flower making. This stuff sticks to itself when you handle it because of the warmth of your hands.
Start with white at the bottom of the leek. Roll tape around a pin.
When you feel the leek is thick enough tear off white tape. Never cut the tape or you will get a seam in your leek.
Repeat till you are happy with the length and size.
Repeat the whole thing with the dark green tape for the top part.
Snip the dark end with scissors to create the leaves. If you like you can add a little bit of brown paint to the bottom to suggest mud or even some thin threads to suggest roots.
TIP : the tape is sticky after you handled it . I like to paint my leeks with a thin coat of Mod Podge Matt to stop them feeling just a bit sticky.
