I agree with everyone else, Just put it away. If the marriage works out, then finish the quilt for them. if not, finish it and maybe give it to a charity to auction. I pray that your sons marriage will work out.
Reading some of the posts it breaks my heart when I read about the wives who leave their husbands when they are in iraq. My niece's husband just left to go to irag and they have 2 small children.My niece pitched a fit that he would be gone for a year. My sister reminds her time and time again. That she had to know being a military wife is not all easy.And that it is her duty to keep the homefires burning.
