I have done my homework.
These stitches are made in the holes from a machine pierced piece of cotton (no thread of course). It was an easy way of finding where to put the needle.
I would say it is a good way to practise, but when stitching free hand, well then my stitches are still uneven. They could be nicknamed 'Long and Short Stitch'!!! Well, I will definitely need to practise more!
Margaret mentioned Redwork, and I had totally forgotten that Back Stitch is the backbone of Redwork. Have I got any pretty design to copy, I wonder...? Oh, yes, I have just seen Annet's charming Sunbonnet Sue. I have some Sunbonnet Sue designs in a magazine... but will I find that rhythm? I will have to review this stitch!
What is your relationship with Back Stitch?
