We all made mistakes on our first quilt. After a dozen or so quilts under your belt, you will look back and say it wasn't so bad. I still look at my first quilt and shake my head and say to myself you've come a long way baby. Just enjoy it.

Quilts cost money to make and you will mess up from time to time. No use fretting over that part. Be sure and take a picture of it. I think your first quilt will become a favorite after time. Mine did. My DD claimed it and it is about worn out. Now it's time for your second quilt!

*** Just love it and use it.

*** My 1st quilt, Garbage Can quilt, was lumpy, bumpy, misaligned but I love it to death.

*** King is a job in itself, have done several, so just go for another.

Just enjoy your quilt and remember-we always learn from our errors-that is how we learn.

To tackle a king sized quilt shows you are tenacious, fearless and confident! I made my first quilt in 1976 and it was such a disaster that I didn't try again until around 1995 when I decided to take a beginner quilting class. That class answered more questions and gave me better skills than any book or internet site.
If you really don't like the quilt just fold it up and shove it in the back of the closet. Don't take it out until you've made four more quilts. You'll be glad you saved it. I still have the 1976 quilt and reminds me of how far I've come in my quilting skills.

I agree with these points -

1. Wash it.

2. Keep it. Ricky Tims includes his first quilt in his shows to show that everybody is a beginning quilter at some point, and we all make mistakes. It's an awesome and proud moment when you look back and see how far you've come.

And one more point that I'd like to add: Learn from this quilt. Think about where you went wrong and what you'd do differently next time.

Congratulations! What an awesome accomplishment! I think you should just move on and start another one. You'll learn more as you go along and get better with each quilt.

Welcome to the board! as you've already found out you are not the first one to make a mistake. So just pull up your quilt and give it a kiss, lick and a promise to do better the next time. You will come to cherish your first quilt. Just like your first child or pet, they aren't perfect but they're yours and you just love their perfect imperfections.

I use low loft poly batting all the time. After the quilt is washed, there is some shrinkage which causes the slight puffiness I love.

Even the best quilters start at the bottom and with imperfections. You yourself may see faults, someone else will only see the beauty and be in awe!!!
