@Mimi, you can use IGP to draw in an image, but CIGP will not let you draw into the application itself. Personally I find it easier to do my drawing in a regular image editing software, like Paint, and then upload it into either CIGP or IGP to see how it looks.
I've been trying to understand IGP for so long now, and this finally helped it click in my head. I think I will actually be able to manage it now!! I do have a single question-- In the patterns, there are some options to choose from already, but is there a way to import a different size and gauge if I don't plan on using the ring dimensions in the program?
To my knowledge, the only way to get a different size/gauge into the program is if you have a pattern for that size/gauge to import into it. I don't think there's any way to just select a size/gauge. Hopefully @Daniel H. is still around and might have a better answer for you.
