Do you just want to know if we think you are being to hard on yourself?
No, I don't think you are being to hard on yourself.
Is it only the blocks in 'the 4th row' that are off?
I would want to know 'why' the blocks are off so I could avoid that challenge on the next Bargello.
Do you know if the blocks in the other rows are going to be off too?
If you haven't made a 'keep it as is' or 'rip it out' decision, you might consider using a basting stitch. Attach enough columns to get you to a decision making place.
If it is going to ruin the way 'you' feel about the quilt you will know what decision to make.
We are going to like it either way you decide. Which way are you going to like it?
