Work Crow's Foot like this:
Mark the fabric with a triangle of even sides (equilateral)
and stretch it in a hoop.
Start at the left bottom.
Go to the top
And back at the beginning. Continue in the same way.
Work your way towards the centre.
DO try to work it tighter and neater that this!
Homework:
Aida Sampler (use a sharp needle and eyeball the holes at the sides, as the grid will not make an equilateral shape)
