I thank your husband for serving his country and keeping us safe.
I don't know what the pattern is that you saw, but I think that it would be wonderful for you to use your stash for a welcome home soldier quilt. It would be especially meaningful because it is YOUR fabric. If you do have to get new fabric, how about online? You can do that when the kids are asleep.
(I hope you have some help with the 6 kids while your hubby is away.)
