I am planning to make a tent with the old yarns for the next skiing. I think I have to reuse it for some purpose. I read an article https://www.junk-works.ca/locations/blog/2017/01/03/10-tips-for-upcycling/ regarding the recycling and after reading this, I thought to make yarn tents with the old yarns. I am planning to make a tent of this model. Hope that this will work out.
