I made Krista Moser's Semaphore Stripes quilt several years ago. It had Y seams and was the first time I had ever attempted Y seams. I watched her tutorial and ones by several other quilters and started piecing. The Y seams were actually easier to do than I thought they would be. Finishes and points were lining up beautifully was so excited. Sewed blocks together, sandwiched, quilted and hung up on display in living room. Several days later I was looking at the quilt and realized that the last rows on left side were not correct. I thought about taking apart and correcting or leaving it. Left it on display and looked at it for a long time. Then my DIL was at the house and said she loved the quilt and commented she would love it. I told her it had a mistake and if she could find it I would give it to her, I even told her it was on the bottom left (I did show her the mistake) but she never found it and she left with the quilt which is now hanging on her entry way wall. I will take imperfection over perfection anytime as when finished it will be loved by someone.
