They would be really neat. I think the jeans sounds like a great idea. I can't imagine trying to quilt such thickness....

It was my FIL's denim quilt that was one of the impetuses for my own quilting. The denim ones are incredibly warm...very heavy.

I like machine quilter over tying - think it holds up better - when washed

I have ones that I have tied that are holding up just fine and they are over 30 years With lots of use and washing of them.

Happy sewing,

this is very true you can make it a nice family or friendly project.
I think that they hold up very well. And that they keep you warmer tied, in my opinion.
