Best selling??????????
Now that I think about it, that would leave out some of the most cherished patterns of all time. If there were templates, they were passed down and never paid for. Not to mention the patterns in newspapers and magazines that weren't charged for.
And at what period of time would anyone have kept track of money transactions.
On a similar bent, I hate when the movie with the most income is touted. Cripes. I've seen Gone with the Wind a couple dozen times. Only paid to watch once. Same with Wizard of Oz. How much did it cost to go to a movie in 1939? 10cents, a quarter?? You can't buy a stick of gum for a quarter nowadays.
