Pattern support queries can be emailed to email@example.com. Please note that the turnaround time for pattern support is currently 3-4 weeks.
All my patterns have been tested and professionally tech edited for fit, accuracy, and clarity, and thus should not contain pattern-stopping errors. Before submitting a support query, I recommend looking through the hashtag on Instagram or the Ravelry project pages for the pattern you are making to see if others have had the same issue and how they have addressed it.
For knitting patterns, you can also visit the Jacqueline Cieslak Designs forum on Ravelry to see if your question has already been answered by the community.
