I frequently make quilts just because I want the challenge of a new pattern or I have the fabric on hand, I am a scrappy lover. I just set the quilt aside when finished knowing the there will be a person who needs the comfort of a quilt. A number of years ago, I had donation blocks, several quilts (3 or 4) finished that I made just to try the pattern and I heard in my heart to give them to a group of mature single women who had been emotionally wounded. So for Christmas that year I gave away 8 quilts. Sure, I had to rush near the end but I also knew I needed to do this for these gals. So, I am all behind your thoughts of making your "just in case" quilt. If they don't leave you can still bless your friends with a quilt for some occasion or no occasion at all.
