Sorry I can't help you... I'm fast approaching 50! But I did start quilting when I was in my mid-30's. Well, that was the first time I finished a quilt.
For what it's worth, the people that I work with - even those who are older than me - think that quilting is for old ladies. Little do they know! And honestly, when I've been fortunate enough to go on retreats, the older ladies are really the ones who are the wild ones!
