What are you most proud of? This project was easy to make, functional, and free as all materials were just lightly used clothing. Rather than fill landfills with millions of ton of textiles, turn your old clothes into something useful. The cover I made of denim is sized to hold a standard pillow. So again - no cost, just use an old pillow. Denim is tough enough to hold up to a small dog and for easy care just remove the cover, throw in a wash just like a pair of jeans. What advice would you give someone starting this project? Everyone has a pair of old jeans. Measure twice, cut once.
