The EZ Quilting Sharon Hultgren Easy Angle Ruler will be ideal for your quilting and craft projects. Made of acrylic, this ruler will allow you to see the fabric underneath. Cut straight lines and perfect shapes by teaming it with a rotary cutter. It is thick enough to prevent the rotary cutter from jumping over the edge. This handy tool displays clear numbers and markings including a 1/4" seam allowance. You can use it and cut 1/2" to 4" of half-square triangles without fabric waste. Squares and attic windows can also be cut using this ruler.
