See the big picture from close up! This wide angle reducing lens viewer lets the user stand close to a design wall or down at the floor and see how the fabric/design will look from across the room. It is perfect for planning a quilt design and handy for selecting fabrics. A great way to make sure your blocks are all turned the correct way and verify that your colors are evenly balanced. One of our very favorite quilters introduced us to this, and she calls it the "green thing" - a very technical name, but she swears by it! Distributed by Cottage Mills.
