Friends did this for their Mom several years ago.
And since then, several others have followed with one or several quilts on display!
At another funeral this past spring, the lady had been working on a quilt, with one block left to finish. They had the quilt at the funeral, and the one last block in her hand in the coffin. Since then her DIL completed the quilt for her. Then her husband (son of) decided it HAD to be shown at the Fair, just as Mom always would have done so. And so it was, winning a ribbon!! What a beautiful story, and perfect ending!! :)
As a sidestep here ... when my husband died, I didn't have the traditional casket spray, rather chose a milker with a bouquet worked in the top of it. We set it on the floor right next to the casket!! His tombstone is not traditional either ... rather an oversized rock from our farm that I had mounted, and with an engraved cow, and our farm name. The traditional details are on mounted on the base.
