The only way I can see to make so many is to almost make it assembly line style and make several of the same pattern.
While that may be fun for some, I don't care to do that. I've never made the same pattern twice. To me it's like reading a book. Once I've done it, I want to do a different one.
Of course, all those speedy folks are what is keeping the charities alive. We need them because if the charities waited for my pokey self, there would be a LOT of cold people in the world.
