In the Calderwood collection, this unique pillow cover is contemporary, trendy and beautifully textured. Some sewing and assembly is required. Using a 4 weight yarn, the pillow shown measures 16 inches square and uses a simple pillow insert. Buttons added can be left to your imagination. Crochet level is advanced beginner to intermediate, yet if you wanted to try it, the stitches are repetitive and fun with instructional photos included.
