Frauke provided excellent service as a tech editor.
Her editing turnaround time was ahead of schedule and my requests for further information were always promptly answered.
She provided the unique viewpoint of a non-native English speaker, both as a tech editor and consumer of knitting patterns.
She provided guidance on layout as well, which was appreciated (especially from the consumer viewpoint).
She helped me understand the changes she wished me to make. It's helpful to understand, so that you can avoid those pitfalls in future patterns.
I would highly recommend her services.
