This is a frequent comment made by judges. It relates to the long verticle or hortzontal seam lines when blocks are sewned together. How do you achieve these straight seam lines.

You alternate the direction that you sew the seams on the long strips.

does this apply as well to long strips of pieced blocks.

Yes.

Yes, it will stop the long seams from curving.

I agree. It is amazing what reversing the direction of stitching will do to straighten out quilts! Just too cool...

I don't sew long seams. I sew my blocks into fours and then the fours into eights. The block seams always match that way and the quilt comes out squarer overall. I only have one long seam in the whole quilt and that's to sew the top and bottom halves together.

I will try this next time, thank you :D:D:D

when all else fails draw your stitching line. sometimes it is easier to follow a drawn straight line; but you still need to alternate directions to keep from getting the curve.
sometimes no matter how careful i am until i grab a pencil and draw that line i just can not get it right.

Hey, can someone explain to me what they mean by alternating directions? I'm just not getting it.
