Take your time - don't try to cut out too many things at once. At first, it might help to do just one block at a time and, when it's done, move on to the next block. With the holidays looming, it is hard to work slowly, but all good things take time. You will get better as you go along, if you aren't too hard on yourself. Perhaps you could give her a box a photo of what the finished product will look like?
