YES!!! I often get an idea and actually graph it out on paper, but am not sure that those measurements are accurate even tho I KNOW the graph paper is 1/4 inch squares. So out comes the cheapo broadcloth and I make a test block. Sometimes the block ends up being too cumbersome (too many parts so has to be broken down futher) and sometimes I just hate the process and scrap the whole idea. I KNOW that taking the time to try out a new or different sized design has saved me mega time and bucks in the long run!!
