We're huge fans of designer Terry Atkinson and all of the patterns she creates. Her instructions are well written, tested, and are great for any skill level. Depending on the fabrics you choose, you can make them look more modern, and keep them very traditional.
Each of her patterns give multiple finished sizes, such as baby, lap, double, and king. And, some patterns over simple changes, like in Urban Cabin, where you can use one piece of fabric for the block center (Basic) or piece together several (Strippy).
Terry uses fat quarters to help you get more fabrics into a quilt and not have to purchase excess fabric.
