Hi, I have done very little true quilting. A small baby blanket, a little piece work here and there. I'm now taking on a king-size denim quilt. Well, first I'm going to make it as a duvet cover and if it's not too heavy I'll add batting and actually quilt it.

For now I'm just worried about thread for the seams. I've read that with quilts it's best to use 100% cotton thread instead of polyester. Is that true? Do I need to use a 12 weight thread for my piecing?

I never actually sew denim to denim; the denim blocks are all separated by a black Kona cotton strip.

The jeans I'm using are of course a variety of shades. Not sure if I should go with grey, black, a medium blue, or try to match the different shades of denim.

Thanks for any input.
