The main reason I have this website is because I love Herbert Niebling patterns and would like to see them preserved. To that end, I collect as many of his patterns as I can find and rechart them. Then I post the recharts for free on the Charts page. This is because, as a friend said recently, the best way to preserve these patterns is in a sort of dispersed archive, where many people save the charts on their own computers. Someday, perhaps, someone will put together as complete an archive of HN patterns as is possible. Until then, this website is my contribution to the "dispersed archive" of Niebling patterns.
You can download the charts for free. I haven't monetized Niebling's patterns by charging money for my recharts. I have overhead costs for this website, which I cover myself. I have a rule to only work from original patterns and never claim someone else's work as my own. I have an original pattern for each one on my site. Any mistakes are mine. Other people rechart Niebling patterns and sell them, producing high-quality work with tech-edited charts and knitted samples. I admit their work is better quality than mine. I rechart as I please and post the charts online in a more casual manner. People who knit from my charts often kindly report back any mistakes they find. I make no promises except that I do my best.
