I know it's too late for the quilt you were working on but I'll give you my idea on labels...I have tried to make each one spedial...using the fabrics from the quilt itself and designing one that goes with it...for my "Trip around the World" quilt, the label looks like a postcard w/stamp in corner.
This was unintentional - my husband noticed the similarity and asked if that was what it was! Then, if I am giving the quilt to one of my "Grands" or "Greats", I have room to add a personal message for them.
