This reminds me of what happened to me a few years ago. Every time I had a dentist appointment (which were always on Mondays due to dentist's schedule) one of our neighbors died the previous weekend. This happend 4 months in a row! Then 3 months passed and I had another dentist appt. Sure enough, another neighbor died! I stopped going to that dentist and found one that was available other days.
In total we lost 6 people we knew that year, 5 of them neighbors.
But as for the quilts, I think it's great that your family has that comfort while they are getting chemo, so I say keep on making them. Good luck to you and your family members.
