My guess is Jane Stickel's Dear Jane quilt pattern in book form. The last I heard there were 100,000 copies sold. Brenda Papadakis is the author.

I'll have to go along with Log Cabin for the most frequently 'made' quilt.

For the most frequently 'bought' pattern, I'd probably go with Grandmother's Flower Garden.

Does anyone know the answer?

my guess is log cabin too

It is very difficult to determine what would be the best selling quilt pattern. I remember quilting from the depression days when Mom and friends had a Quilt Guild. They worked on 9 patch, 4 patch both with sashes, Grandmother's flower garden, Pickle dish, Wedding ring (both double and single), sometimes applique, mostly tulips and roses and square on square for the wool quilts. There were no purchased patterns that I know of. They just traded patterns back and forth for the quilt the Guild was working on at the time.

If I had to choose what the best selling quilt pattern is, I would pick Trip around the World.

That's a good question but I have no idea what the answer is. I know during the Depression era they had patterns in newspapers but I've never seen ads for them being sold. I have several books by the historian Barbara Brackman but they are about fabrics. Super interesting!

Elanore Burn's Log Cabin revolutionized quilting. It's popular. My vote goes to oldies like Double Wedding Ring, Dresden Plate and Grandmother's Flower Garden...ones ladies could sit and hand sew. Also a Scrappy Quilt was very popular.

As quilting has been a part of history for so long, I'm not sure that could ever be determined. Lots of possibilities have already been posted, but I don't think you'll ever know.

Most websites that sell patterns have a "best sellers" tab.

i really do not know but i wold say that gmfg would be my vote

I would say a Log Cabin, or a stripped star.
