My Hexies shown on my previous post are approx. 3" across from straight side to straight side .
I'm joining my hexies with a stitch one way then going back across the seam which makes it like a cross stitch . A nice little project to keep in your travelling bag . If you enlarge the hexie you will be able to follow my pattern quite easy .
4 chains to form the ring
Then 12 trebles into the ring.
from here if you have enlarged the single hexie you should be able to carry on.
as the Meercats say , simple .
