Why would you ever want to do that? Word is .doc or .docx format. PCStitch is .pat format. They are not compatible.
You can "print" to create a PDF and then maybe use a 3rd party product to convert the PDF to a Word document but I just don't see that it would improve the pattern in the least.
I agree wholeheartedly, Diane. Charts print brilliantly directly from PC Stitch. If you try putting them into another program, you can actually lose some of the formatting and detail - not worth it.
