WOW!! 126" x 140" sounds like medieval-tapestry-sized!

I feel your pain - my first quilt was a 110" x 110" watercolor quilt of a live oak tree surrounded by azaleas...if I knew then what I know now I would never have made it! I can't remember the exact number of squares, but it was something like 3600...fortunately they were relatively large pieces (1.5" finished), and not like some of the postage stamp quilts you see, where they've used 1/2" squares!

84 x 96" could not make it any bigger as daughter wanted it made into a doona/quilt cover.

My largest (my first and only that size) was a Harley-Davidson T-shirt quilt for my son. It was a project from, well, I think you all know where.

I was asked if I would make another and the response was......"never". That one was for my younger son and it was a one of a kind....used 53 of this shirts, some of his wife's, his nieces' and even a H-D child's purse is one of the block.
That block can still be the holder of mementos since I left the flap open.

No more biggies for me.......love lap size or hangings.

My first "real" quilt was 120x120. It was Sunbonnet Sue and I embroidered every other square. I did it sitting with my embroider machine sitting on the floor. What a job that turned out to be! Since then, my largest has been about 90x90. I do a lot of QFKs quilts and love them because of their size :)

The largest quilt I ever made
 

[
It was a king size bedspread. This was for a friend in 1985

The largest i've made is a king size, never again,i found it to be much to much for me to handle i enjoy making twin or lap size

120"x120" using the BQ (Big Quilt) Pattern. The big blocks are all fussy cut huge Hawaiian flowers or foliage. It is pieced, sandwiched and partially quilted. I'll finish quilting it in the next few weeks as it's a late Christmas present for my son and his partner.

This is the last one of this size I will ever make -- too hard to quilt on my home machine. I'm really into wall hangings or laptop quilts now.

My largest was a king size quilt 110 x 110 that I quilted on my DSM, long before I even took a quilting class or even a machine quilting class. I don't think the second king-size quilt was much bigger, if at all.
