This is one my charity projects, pet quilts/pet mats for our local animal shelter. I tend to use scrap fabric or fabrics donated by people that I know. I just got a great haul of upholstery fabric.
In the above photo, the center block had matching fabric, used on the corners. Then I found some coordinating sashing. The outer border is made from three separate fabrics. All the fabrics had different textures. Hopefully, the animals find that interesting.
I discovered that I didn't have the skills to get sharp points with thick upholstery fabric and that my math was off, so the borders do not match nicely on the ends.
