Worse than losing details, if that red line is not in sync with the design, you have something that is not as professional as you would like.

At first, I thought that the digitizer had not done a good job. Then I realized that the fabric had actually moved 1mm creating a gap between the body and the detailed outline. 

I normally would have placed a basting stitch around the kitten but in this case, my software allowed me to do an "offset." Offsets can be used for emphasis, outlining or basting. I did set the stitch length at 4.0mm so that it will be easier to remove upon completion. If you forget to place a basting stitch on your design, you can add it from the 'frames/outlines" available on your machine. Just be sure to add that section on at the beginning so it can do its work as you go.

With all my expectations of a perfect project, I do need to remember that preparation is important. A stabilizer is needed in this instance as well, I have always said, it is difficult to 'over stabilize' but 'under stabilization' is a disaster in the making.
