when I block a quilt I pin the corners to the carpeting and then I spray with water while patting, patting, patting in place LOL, let completely dry and then press...

add borders and put the borders on the right way...measure through the middle, cut your borders then pin and sew from the middle...may work

I would get the top wet (saturate in the sink as above poster suggested), get as much water out as possible, and lay out on a dry towel on the bed....get a long straight edge and use as a guide to straighten the seams, pinning through the top to the bed (straight down with the pin, just to keep position)....when all seams are pinned straight, let air dry....this might help put it back into square.

I've done a lot of quilts that use this strip technique and I have found the error is in pressing ( and inadvertently stretching) the seam, rather than sewing in the same direction. I've experimented different ways and have never found sewing direction to be a factor - only incorrect pressing. So I agree with the others who say to wet it, and re-press it. I have drawn a line on my pressing surface to help me keep the seams perfectly straight, and it does help. Good luck!

Carefully fold and pin the top of the quilt to a wire coathanger or use a skirt hanger. Then get the top soaking wet - not just damp - and hang it outside to dry. The weight of the water should semi-block the top so it's more square.

I think I would take in the seams a bit where the quilt is wider. Just go back over them and taper a few seams a very small amount. Overall, it should add up to the 2" that the wider end has.

Ive done the ripping but will try the ironing next time if it happens.

I wish I could do this but I'm far too anal. The bend in this beautiful little quilt would drive me crazy. So, like it or not, I'd rip out every seam and re sew it.

But whatever you decide to do will be right for you!

I would try wetting it and pulling it out so that it lays flat and straight and let it dry. If it's still a tiny bit off, a little artful pressing should finish getting it all squared up.

I like the idea of cutting it into squares. I'd then arrange the blocks so some of the curves run north to south and some east to west, alternating and turning them until you get a look you like. I'd use sashing the same width as the strips in your blocks, to give it symmetry and draw attention to the curves rather than trying to hide or fix them. I'll bet you would get one spectacular quilt. Some of the best designs result from mistakes! Just stop stressing and have fun with it!
