I agree with Scissor Queen. Your daughter will go on to another school and this will be behind you. As the book says "Don't Sweat the Small Stuff, it's all small stuff" and in the scheme of life this is one of those small "stuffs". Take care.

Ditto to this. The teacher will not expect perfection and being for mostly children will probably expect something that is not perfect.

Go with the flow. Take a deep breath and just do it. Like many others here have said, no one will know if the seems are 1/4" or not.
It is a labor of love and doensn't have to be perfect.
The kids and all involved will love it. I'm sure they appreaciate all that you are doing for this project.

The best thing that I can suggest that you get together and help finish the blocks. She should see how important the seam allowance is. I have one other thought I was asked to put together some blocks that definitely were not the same sized. I was watching Simply Quilts that morning. Alex said we can all face that problem when different quilters combine blocks. She showed what she had done to solve this. She took small and I am saying about1 inch strips of something bright and carefully sewed it to the smaller ones. When she showed the finished top it was so pretty and just added to the design. I hope you get a lot of good ideas to help you.

I understand that you would like to present a perfect quilt, but in this case it seems that the real "perfection" is the message done by the children. I'm sure the real beauty will be conveyed and your thoughtfulness in doing such a memorable project will be so greatly appreciated.

don't sweat it. it's to be a "fun" quilt. let it go and finish it and smile,big!!

Yep, it's the intention, not the outcome that is important. The imperfections just make it all the more authentic.
I taught for 24 years (K&1st Grade). We made quilts all the time. Perfection had to go out the window. If you altered a child's block, or a participating adult's work, you are telling them it wasn't good enough. That is not incentive to keep on trying.
What you are doing is validating all the creative spirit of those who participated - an honorable, if exhausting, labor of love. It's good to know that what you send out into the world comes back to you threefold! Don't stress. Breathe. Enjoy!

I have assembled many group quilts and everyone has their own idea of size (no matter what is specified). The very first one I did was a Christmas quilt made with 4 patches and each quilter made 6 blocks of a certain size. Well...so much for each one being the same.LOL But I trimmed and assembled and everone loved the quilt. It was far from perfect but made with LOVE and that's what counts.

It's hard isn't it? But in the end, it is a quilt "made by" children, so I think those imperfections will make it that much more charming. It's a great idea and it will be hailed as wonderful no matter the quirks.

:thumbup:

I agree with sissor queen . The teacher will see a quilt made with love not a few wonky seams,it really dosnt matter.
