I went back to your post of the picture of this quilt and I certainly can't see it in that picture.

my vote is to leave it, the only perfect one is God. Your DSIL will be so pleased with it she won't even notice and she will love you for taking the time to make her a quilt.

It was the side of the first row which is not seen in the picture. I decided that I will applique over the two oopsies when I finish quilting the rest of the quilt. Off the frame I will be able to baste the corrected HST in place and then quilt it to match the rest of the quilting. I will feel so much better about it. Thank you all for your comments. I thought about leaving it as is and just can't. It will haunt me:o

Since you checked it over several times, put it on the frame to quilt and had started to quilt before you noticed it then it is not noticeble at all so leave it and don't tell anyone. It will look beautiful

Non-quilters won't notice. Just go with it and don't tell them you goofed. They will never know.

That's too funny. One of my very good friends says that all the time, but I've never heard anyone else until now.

..my modern equivalent of riding past on horseback is to take my glasses off - does the quilt look OK in soft focus? If so, it'll do!

I think every quilt I've made has some OOPS somewhere. But I'm not perfect even though my DD says my projects look perfect to her. I agree with so many here.... if you didn't notice it before you put it on your frame, others won't even see it.

for the block you want to replace you can make another square and hand applique it right on top and after its quilted it will not be able to tell

About 5 yrs ago I made a version of an Irish Chain and after it came back from the quilter I realized that I have made a mistake and turned a block wrong. The quilt was for my DD and she loved the quilt even with the mistake. I really had forgotten about the block until recently my 10 yr. old grand daughter took me to the bed room and showed me the mistake. It happened to be almost in the middle of the bed. Quite embarresing for a 10 yr. old to point out your mistakes.
