This tutorial shows you how to change a picture/image into a cross stitch chart in Photoshop, I thought that this tutorial would be really good for the sort of thing I want to do for my pattern but I found that once I had created a cross stitch chart on a photo, it didn't look as clear as I thought it would, I don't think that it is up to the standards that I need my cross stitch pattern needs to be at.
Here is my attempt at a cross stitch chart.
