Do you ever
 

I was ‘gifted’ scraps/ yardage from a deceased quilter’s family. Not all are cotton however. I can see the quilter cut pieces from the poly/cotton or permapress. Do you ever mix other fiber contents like this, with your cotton pieces?

I have used different fiber fabrics together, it just depends on what I'm trying to achieve. If the fabric is flimsy, rough, or just outdated, I will take it to my guild were one of our members used them for stuffing for animal pillows that she then donates to the local pound.

I made an interesting Crazy Quilt will all kinds of fabrics and blends. The quilt came out great! There are good places for mixed fabrics in some quilts.

Yes, I do.

I don't mind a whole project from non-cotton fabrics, but I won't mix them, just too many unknowns about if they would "play nice" together

I never have but I don't think there's any law that says you can't. :)
I'm always concerned about the integrity of the fabrics. With all cotton you pretty much know how they will behave.

I used cotton and poly/cotton (wash & wear) years ago. My late Son had one from many years ago. The poly/cotton was still there along with the poly batting I used. The cotton was totally gone. The quilt was made before I knew much about quilting.

I still have some poly/cotton I plan to use for my donation quilts. Just don't know when.

I prefer working with cotton but that was mostly learned. Starting in the 70s as I did (and earlier), the magazines at the time had a lot of positive things to say about using poly cotton fabrics. The durability, the colors, the sharp printing, the lack of ironing, all were positives. My biggest negative is that they are slippery and treacherous!

I will still use poly blends in "use" quilts, those meant to be taken in the car and used for picnics, or wrapped around a child who somehow got wet, or whatever needs you might have. I have a large funky piece of border print that I just love and I'm going to use it to back a scrap quilt that I am keeping for me. It may or may not last 10-20 years, can always put on a new back later if the top is worth it, but that's not a show top either.

For the last 20 or so years most of the fabric I buy is from estate sales or thrift stores with no labels. I've gotten really good at burn testing fabric. Nowadays there are videos but it is pretty easy to learn. Burn a piece of what you know to be quilting cotton. It should be fairly hard to light, not smoke, and leave a soft edge with maybe a little grey ash. Now burn something that is poly of some amount/type. First, be careful because it with light quickly and can burn brightly. t will smell like burnt plastic. It will have a hard edge, maybe with little pills of melted stuff. Smoke will be black. Wool and silk fibers will smell like burnt hair.

There are some rayons (made from plant fibers) that feel and burn surprisingly well and if they otherwise pass my tests I will use them despite my suspicions. I have one top that I made from actual scraps including clothing, and had a piece from a favorite rayon sundress that got a large stain. That used rayon lasted better than some of the fabrics I bought new in the top!

I never have for the fact that some fabrics may shrink or stretch where the other fabrics will not. Only in crazy quilts have I seen different fabrics used.

I often use mixed fabrics in wall hangings. I've had to recognize that poly satin will behave differently than cotton, usually stretching a bit and looking puffy. Polyester is a stronger fiber than cotton and will last longer, but it does behave differently.

I have a quilt from the 70s that is obviously a poly/cotton blend. It is still going strong, in spite of being used on the couch by the kids and dogs almost every day. So, I am not opposed to using poly/cotton blends in my quilts. I just don't like to mix them.

I have when I was finishing up a friend's mom's ufos. Her fabrics were poly/cottons which I guess was what was available in her area at the time. I used cotton. The only difference I noticed was the stitches skipped in the poly cotton. I just went slower with a sharper needle. It worked better but still skipped.

I do all the time. I am not a purist . I always think of our ancestors quilts - the purpose was to make something warm and usable out of old clothes and other things. They were beautiful! Some of my old quilts ave wool and velvet in them. The sad thing about so many of the old quilts is they "rot" as my seamstress grandmother would say. She meant that the cotton fabric broke down. She also would be sewing and throw out spools of thread because it was rotten. Collecting odd threads from thrift stores and estate sales, I see this all the time. Cotton thread breaks very easily and the poly blends are strong as ever. Same with fabric. I wonder if future generations if these beautiful cotton quilts we all are making will be holding up.

I will use polyester/cotton blends - but I still prefer to use only one type of fiber for a top or backing.

Thinking about it, though, I've used polyester battings with cotton tops and backings - and did not give it a second thought.

My one & only time I did was making an old fashion crazy quilt-I hated it lol My brain is way to anal to have everything all mixed up...lol Sorry I wasn't much help was I?
