Happy Kittys Table Topper is designed with the Creative Grids Kitty Cornered Tool. It is a great choice for a class to learn how to use the tool. The twelve-inch blocks showcase the technique, and since there are only four of them, it truly can be finished in an afternoon. The Kitty Cornered Blocks are combined with a center square and rectangles like a nine-patch. Then they are separated by sashings and a corner-post which create a secondary center design. Choose three coordinating fabrics and begin! 36in x 36in. The Creative Grids CGRDH5 is required. The CGR24 or CGR24LEFT and the CGR12 or CGR12LEFT are recommended. Project Time: 2-6 Hour. Fabric Type: Yardage Friendly. Project Type: Home.
