wrinkled fabric
 

I have sewn and quilted a quilt. I used Koni fabrics. When I washed the quilt one of the fabrics was all wrinkled. What can I do? I have always used koni fabric and not had this problem before. The fabric didn't sink.










after

Is it really horrible, or just a little crinkly? I wonder if placing some heavy books on it for a while might make it relax.

This is why I think it's a good idea to pre wash, especially non-traditional quilting fabrics. You can try to press it with a steam iron (not sure of the specific fabric content), heavily over quilting that fabric, re washing and drying flat, smoothing out those areas, or just leave it and call it a design decision!

It's all cotton

In my experience, severely wrinkled fabric after the quilt is completed is usually a sign that it was not quilted enough. Just because your batting says you can go 10" between quilting lines doesn't mean you should.
When you wrote "koni" I am assuming you meant Kona fabric which is Robert Kaufmanns line of solids. Solid fabric will show the wrinkling a lot more than a print because there is nothing to camouflage the shadows and highlights caused by the peaks and valleys of the wrinkling. Just like quilting will show up a lot more on a solid than it does a print.

You can try re-washing the quilt or wetting the offending area and then blocking your quilt and let it dry flat. Then I would go back and put some more quilting (probably a lot more quilting) in or this will be a problem the life of the quilt.

I agree with feline fanatic that more quilting will probably solve the problem.

I quilted four inches apart. It was kona fabric and all the other fabrics where kona solids. So why the difference in the other fabrics. The other fabrics are not wrinkled.

it is a possibility that some other fabric got mixed in with the Kona cottons at the store.

All Konas are solids. http://www.robertkaufman.com/fabrics/kona_cotton/ There used to be a manufacturer that specialized in Asian prints called Kona bay but they closed up shop last year. This most recent post has me confused as you are writing like the one that wrinkled was a different fabric from all the rest because you refer to one as "kona fabric" and the others as "Kona solids".

If you believe all were the same brand and same fabric (all solids all Robert Kaufmann Kona cottons) and you quilted no more than 4" apart in all directions, then I don't know what to tell you except perhaps Bear's suggestion that they got mixed up at point of purchase. I do know I have seen employees at JoAnn Fabrics roll up non kona solids on the bolt marked Kona. Witnessed it with my own eyes, brought it to the employees attention and she just looked at me and said it doesn't make a difference. That was pretty much when I quit shopping at JoAnn's

OK, need some clarification. Kona cotton is a solid color fabric by Robert Kaufman. Koni is a manufacturer of upholstery/table & bed linen fabrics. Which is it?
