It looks great but I don't like the price...I do the same thing with a credit card held down by blue tape or moleskin...you can use an index card to measure...the lines are 1/4" apart exactly so can just punch holes at appropriate spot and put under needle...Bonnie Hunter sells a plastic small piece that has the hole measurements for around $5...I would love this if their price was more reasonable...$50 is too much for me
