finding the diameter
what is the easiest way to find the diameter of a blank? i just wrapped a paper around one and marked it where i could see the other paper and it came up at a inch around. but for some reason that doesnt look right to me. i am looking to get some grips for this rod i want to build but dont want to order the wrong size and then have to deal with shipping grips back and getting new grips and all that. so what is the easiest way?
