my wife is amazing with building furniture, crafts that she sells for $40 a pop, and all around general woodworking. She sells her stuff on Facebook. I am thinking of getting her an iPad Pro with the Apple Pencil. I think it would be good for her designs, I am just ignorant of what software apps would be available that she could use for designing. In a perfect world, she could draft/sketch would some of her furniture/wood working would look like and then email to a customer before an order is placed. Could someone point in the direction of an app she could use? Thanks!
