Coordinates with the Linen Looks (http://www.spoonflower.com/collections/70120) and Painted Linen (http://www.spoonflower.com/collections/82033) Collections! Please check out my other Tea Towels here (http://www.spoonflower.com/collections/289456) if you would like to see the set or visit my blog for inspiration ( http://www.jolenebalyeatdesigns.com/vintage-tea-towels/) or a tutorial ( http://www.jolenebalyeatdesigns.com/bon-appetit-french-script-napkin-tutorial/) on how to sew these up! The tutorial is for making napkins, but I used the same process for mitering the corners of these towels!
