Even the pros have the dreaded V problem at times. It takes very accurate placement of the ruler and the folding of the fabric. The least expensive tool to try first is the one I had great luck with; the June Taylor Shape Cut. I then went to the Shape Cut Pro for 44" strips and then on to the Alto Quilt Cut2 and now finally settled on the AccuQuilt die cut machine. I'm getting old so I can splurge on quilting whims.
