Can you post a picture of it? Or describe what pattern and size it is.
I recently took a quilt apart that was tied to replace the batting. I wasn't thinking and didn't wash it before taking it apart and washed it on the delicate setting. Since I have one of the new top loaders and it goes not have the center pillar it came out okay but it did stretch it a bit. After thinking about it I thought I should have basted the quilt together like a pillow case except sew all three sides.
