Clipping seam allowance?
 

I'm trying to peace togther rows of log cabin blocks, I just had to rip, rip, rip out the length of my quilt, so I can get my seams to match. I've been pinning them but when I sew them they jiggle out of line. I think the problem is that both seams are going the same direction instead of opposite. Do you think I should clip it so they go opposite direction and they can nestle in together and match.... I hope I explained myself OK.

I'm not sure if clipping would work. I'm trying to visualize this. It seems to me that if you have your blocks in rows and are on the final stage of putting the rows together, it would be better to go back to the pressing and press the block seams within the rows to the opposite side. This would allow you to better lock the seams together.

It is easier to match seams when the seam allowances are pressed in opposite directions, but it is still possible (and very often necessary!) to match them when they both go the same way. I would pin more often, and at right angles to the seam line, and sew slowly and carefully. That should work - good luck.

I agree with this advice. But sometimes, I have clipped the seam allowance to allow the bulk to flip in the opposite direction. I don't like to do this, as it makes a weak spot near the seam.

I have often "flipped" my seam in the middle to make it nest at each end. I didn't need to clip it or anything, just press the flip-point. Have had no problem with "lumps" on the front side when its finished. Otherwise you could press your seams open - would be a pain but lots of quilters do it now.

Flip the seams in the middle.... I never thought of that and it just may work in my case. Re-pressing them in opposite directions won't help in this case because the seam is sewn within the block on the other side. Pressing them flat while flipped wouldn't cause as much bulk as both seams sewn to the same direction.

Thanks everyone for your suggestions.

Good luck' let u's know what works!!
