Duvets for sewing projects (Spring Lane estate, Canterbury)

I have two king size duvets where one is all white and one is pale sky blue on one side and white on the other. The blue one is made up of panels 9"/7.5cm wide. Both are heavy cotton or polycotton but have slight paint splashes on them. They have both been washed. They could be used for sewing projects but not as duvets. Collect from Spring Lane estate, Canterbury.
