Well, I managed to 'scribble' on the fabric without breaking the thread. That's a good start.
Now for something a bit more complicated - satin stitch. That worked okay, although it's going to take a lot of practice before I get it really smooth and consistent. And the fabric puckered in the centre.
This time I remembered to back the fabric with stabiliser and it is smoother, even though it doesn't look like it in this photo. I prefer the colours in this sample.
Let's try going around in circles. Well, a spiral to be more accurate. That's not too bad.
