Researching experimental stop motion techniques- sewing

I came across these 2 videos and was amazed by them in particular the last one. I understand how they were both made but they must have took ages- I watched a video on how they made the advertisement and there were over 10 men making it!
The advertisement looks very professional but I like the organic and rough qualities that the first stop motion has too.
After seeing these I am quite interested in making a stop motion using sewing techniques to see if it works well.
