It happens, when it does I just snip it and press it so it lays the right way, so that it is not such a large bump to quilt over. I agree setting the seams seems to help, no pun intended... LOL

I hate when this happens so here is what I do. When I'm setting my seams before pressing them to one side, if there is a seam where the seam allowance is pointing the wrong way on the bottom side, I put a tiny spot of Elmers school glue just at that spot. When you then press the seam to one side, that little sucker is glued down and will not give you a problem when you sew over it. The glue washes out, the frustration is gone and it's quicker that re-sewing any twisted seams. I usually repair seams when I do them twisted and it bugs me every time so this way cuts my stress level!

I have this happen sometimes to but I don't let it bother me. The front looks good, then I am fine. I do not spray starch any thing on my quilt. I love the softness of the fabric and batting. I tried it one time and sewing with "cardboard is not my thing. In all the years that I helped My Grandmother make quilts, not one time did I see her starch her quilt blocks or quilts. Just enjoy the the quilt making. There is only one who is perfect!

I'm with you on this Comice! I discovered that the front part of the machine that opens for the bobbin had a gap in the height from the plate with the feed dogs. i was able to put a shimabout 1/8 inch) under the section that was lower. So now the machine lines up fine, but I still get the twisted seams. I just iron them into submission. No ripping out or I'd never finish a quilt! Besides, I'll be dead and gone before someone tries to check the inside​ of my quilt!:D

I so admire your precision! One of the quilters in my open class showed us one of her WIP's - a very pointy complicated kind of log cabin - and the back was beautiful! My quilt backs were not so pretty - flipped seams, ravelley fabric, trailing threads etc . (Of course I am not in quilt shows and going to be a judge like she is) I wanted everyone in class to admire the back of her quilt. Now I am trying hard to make my backs better. I bet you find it easier to quilt the top knowing your seams are in order.

Love the Clover fork pins. Costly?? Depends on how much the twisted seams bother you.

All the replies to my question have been greatly appreciated and I've learned something. I just love to quilt and I'll try harder using a stilleto to get my seams straight but in the end, by the time somebody checks the inside of my quilts, I'll be off-planet. I feel better knowing I'm not being a complete failure by not having my seams straight. And kudos to those who do fastidious work. I really admire the quality of precision as I careen my way though life. But, try as I might, I'll never be one of the precise ones. And that's just perfect for me. Isn't it wonderful to be a quilter?

I find that if there is even a slight ridge on the machine where it meets the cabinet I have a problem. A piece of green label Scotch tape placed over the ridge stops the problem. Cheap, easily replaceable when I have to change the bobbin and makes a real difference.

I'm glad this came up - being a new quilter, I just figured (sigh!) it was one more hurdle I would have to learn to get over.

Ditto for me too tartan! Exactly how I do it.
