Stars/back stitch on aida

Start your stitching at the centre of the star. 

Make your first stitch in the hole directly above your first one.

Come back up the fabric in the next hole directly above.

And come back down here.

Repeat this until you have gone up enough squares (usually 2 or 3 for the stars). 

Come back to the centre and repeat for the other 3 straight lines.

For the other lines start diagonally across from the centre.

And come back down into the centre hole.

Start your next stitch diagonally across from your first. 

And back down diagonally across (this is also a half X stitch).

Repeat this on the other diagonal lines.
