Cushions from scraps

Awhile ago I was graciously given a garbage bag choc-a-block FULL of pure natural dyed wool. I didn't have much use for the scratchy wool so I picked up one of my old better homes and gardens magazines and created four squares into the beginning of a cushion cover. At this point I have run out of the wool so I plan to make up the remaining space with sewn calico, I think it will match the natural colours nicely. Thoughts?
