I myself have fudged but that looks awful close. I would hate for you to get it all done and then within a month or two have it come apart.

I would rip it. I have gotten very fast at ripping, lots of practice.

Rip and redo, sorry!!!!

you can rip it out and sew a piece on the sashing it won't be seen by anyone but you then put your sashing back on

I always make do with whatever I end up with. I've had a couple of quilts that I've had that happen to. I restitch the seam using a very short stitch length, it's a number 1 on my machine. Then I sew a second seam using a very short stitch length right next to the first one just a milimeter away from the first seam on the raw edge side. If the fabric is thin and tends to ravel, I also make sure that the quilting stitches that seam down well too so that it takes the stress. I've dabbed on a little Fray Check, but I have to be careful to just let touch the seam allowance. Otherwise, it'l make a spot on your quilt, so I don't do that anymore.

DITTO what she says!

Usually I don't do this unless there is at least 1/8 of an inch. I have fusible featherweight interfacing and when I am a bit short, I fuse it on and then stitch over. Looks like a close call. Can you come in just a tad more in your stitching??? Just a thought. I HATE having to take stitches out because it really isn't ripping, it is surgery !!! :)

I would not take out the seam. Instead, I would do a tight zigzag stitch with the left side lining up with your existing stitch and the right side covering the narrow seam allowance.

I think you already know what you "should" do BUT if you choose not to rip than I definitely would reinforce your 1st stitching with a smaller, stronger stitch. Good luck with that.

I couldn't cope with the worry of having it come undone.....and I would have to fix it....so here's a little push from the Land of Aus.
