Looks like several of us are the "late bloomers" at the end of this list. I have made couch throw size that is long enough for snuggling for graduation.
I admire those who want to send their grads to college with a hand-made quilt but for the hours and money put into a quilt, I'd never do that. Your grad may appreciate the work put into such a sweet gift but that quilt is going to be so mistreated, misused and maybe even stolen or put in the trash, I'd buy one of those bed-in-a-bag sets and have them leave the sentimentally hand-made one on their bed at home for a keepsake.
