Keep going with this quilt, as the others have suggested.

I discovered, like you, that using a 1/4" foot on my machine is not, in itself, the fool-proof way to make a 1/4" seam. It does keep the right edge of the fabric lined up nicely as it goes under the needle. I learned that I ALSO needed to move my needle two settings over to the right because the standard needle position on my machine is for garment sewing. But it took me a while to learn that fact, and it did cause a ton of frustration when my blocks were too small.

Don't worry about the seam width. Mary Ellen Hopkins always called it 'your own personal seam allowance'. As long as it's uniform, it works. Your quilt is beautiful!

Ditto, the quilt is beautiful, and you should finish it. Just keep on keeping on, no one but you will ever know your seam is over a 1/4th inch but you and us of course and we won't tell the quilt police.

I would finish it to a more complete point in the design. If you don't turn it into a bed quilt, it will still make a beautiful display piece.

Awesome Quilt.. I would finish it!

I would finish it and try to figure out if I can correct the seam allowance for future quilts. There's nothing wrong with your quilt, it's beautiful! It'll just be a little smaller than planned, but that's no reason to quit now.

It looks great to me. It would be a shame not to finish it. Don't worry about perfection - it doesn't exist for us mere mortals!

Definitely finish it, it's beautiful!

It will be beautiful and you have learned something. Try your new knowledge on the next quilt. I have made over 118 quilts - trying to make the perfect quilt. I have not made one perfect yet, I just keep trying. I have improved alot and still have a way to go.

Please continue...the quilt is awesome! You are way to harsh on yourself. You have a gift.
