How I clip a twisted seam -
 

A twisted seam bothers me - a lot. Sort of like wearing my underwear on backwards and inside out. (Usually not life-threatening, but not very comfortable, and it would erode my self-confidence - even if no one else knew about it.)

This is how I clip a twisted seam. I then put fray check on the clipped parts.

I think that clipping each seam allowance separately helps preserve the seam strength more than just clipping both seam allowances at the same spot. (I may be wrong about that, but this is my thinking at the moment.)

I've never used Fray check- is it permanent? I'm assuming it is. Thanks for sharing.
Twisted seams only bother me if I have more than a couple.

Fray Check is permanent - and it leaves the fabric stiff where it was applied.

I think there are products that leave the fabric feeling softer, but I don't know what they are.

That's good to know. I know I have Fray Check somewhere but as I said I never used it :)

thanks for sharing... to me, the clip,is too close to the seam. i'd rather have the little lump that would likely be absorbed into the batting..JMHO

Front view:

Fray Check in my quilts is mostly unnoticeable. After it's finished, you can hardly find it unless you know it is there. And it only needs one tiny drop to do the job there.

I really like you method Bear. I never thought about doing the double clip. I have been doing that clipping very close to the crossing seam so it is barely noticeable even from the back.

I don't like twisted seams at all. Thanks for your suggestions.

Fray Block is the other one that is more pliable. It isn't stiff.

I leave the lump but I do like the idea of using Fray Check when necessary. Also, your clipping them separately. That's a great idea.
