I finished crocheting this just now and I'm very satisfied with it! My arm feels like it's going to come off anytime now! It looks very pretty if I'd say so myself :p
For the back, I just crocheted a basic granny square using red, ecru and white yarns. Then I sc all around to attach them together. It is a bit crooked though I don't know why. Might be because of the pillow form inside.
For the closure, I sewed colorful buttons on. They do look very sweet. I will make another one of this cushion cover but a bit bigger by adding an extra row on each side. What do you think?
