JoAnn from the DIY Maven created an envelope enclosure pillow with a large button. It looks like she used a velour but you could use any fabric – canvas, burlap, cotton, etc. to add a little flare to your bedding, couch or chairs.
Her original inspiration was the Textured Linen Pillow Covers from Pottery Barn which retail for $25.
