There are several tools designed for the purpose of making the holes on the edges evenly spaced. There is the Skip Stitch blade, EdgeryDoo, Edge Perfect Blade, and the Simplicity Deluxe Rotary Cutting Blade Blanket Stitch. There may be others. If you google any of these you will find tutorials and illustrations for their use and projects to use them with and also directions for the edging patterns. In addition there are examples at Project Linus and patterns. I made several drag around projects for my grandchildren when they were little. Now they are getting big enough to start requesting quilts. There are also some leather working tools that I would think you could use for the same purpose. I know my dad had some that made evenly placed slits in leather when hit on the top with a hammer. Don't know the name of it but if you have access to something like that you may try using it instead of investing in one of the blades. Ann in TN
