I found an awesome product called "Clearly Perfect Angles" made by New Leaf Stitches. It is a vinyl template (no adhesive!) that sticks to your sewing area and gives you lines to sew perfect angles, as well perfect 1/4" seams. I have a (supposed) 1/4" foot, but it's actually slightly larger than 1/4". I'm just now completely my first project wit hthis new tool, a Half Hex pieced quilt, my seams were ALL the same size thanks to this tool and the many pieces, fit together perfectly. I highly recommend it!
