They are worth every penny and MORE! If you can go to a show where she or one of her Certified Instructors is vending (A Studio 180 Design booth), you can get a "show special" price. I have every tool (not ruler as you don't use them to measure) that she has and use every ONE with exception of Tucker Trimmer II. I have yet to find a pattern or block where I am using 1/4 and 3/4 inch measurements. With her short video tutorials, if you forget how to use them (can we say older brains don't always retain info as well as they used to?) you can pull up the YouTube video to refresh your memory.
