I did exactly that, made a quilt (actually two for twin babies) and gave them knowing that the quilts would probably be left on a park bench someplace. but, I thought it was worth the effort to express love in a way that hadn't been shown this woman. I never heard one word, no thanks, no mention of the quilts ever. That's okay. I loved her in a real and tangible way, what happened to the quilts doesn't matter. I did make a simple pattern though and used washable fabric.. I didn't make an heirloom because I knew where they would probably end up. I don't think that diminished the gift, it was just a wise choice. Go ahead, loving someone is always worth the effort!
