Chapter 2, Task 3. Translating into Stitch - white on black.

Chapter 2, Task 3, The original ink washed background with white charcoal pencil is the top image and my white on black stitched sample page is below.
I began using cream cotton (I had ordered white)  and ran out so completed the sampled with new white cotton - the first image was a long way off the original, the second wasn't great - the only way I seem to get a more accurate result is to draw the image on the fabric first and then stitch - not sure of this is okay to do?? The contrast is really good and definitely enhances the images in the reverse. I had problems with the stitching in the final image as the bobbin grabbed the cotton and I had to re thread, then it went straight back to normal. Pleased with them overall and pleased with the way my machine is performing now it has decent cotton!
