I have not shared the pattern with anyone. I haven't seen anything like it on any pattern Web site. However, since I made it from a source image, it's possible that someone has worked from the same source image.
Or maybe you have just seen the source image, and that's why my image looks familiar to you: [link]
If you have a link to a similar pattern or pumpkin, feel free to share it. I always like to see what other people are doing.
I was browsing The Pumpkin Wizard, and I found the pattern that you might have seen. It appears to have been made from the same source image as mine. I didn't know about this other pattern when I made mine. (If you look closely, you can see the differences. Mine is a lot more detailed, and I rounded the image so that it did not appear to be cropped.)
