Your Grandma's quilts are so bright and colorful! Thanks for showing.

What great replys. Thank you all.

I know that they have improved the quality of polyester thread and fabric but there is nothing better than 100% cotton at least in my mind. Too old to change.

I used a poly/cotton for the backing on a donation quilt. It slid around on the batting making it impossible to fmq without getting puffs and puckers. NEVER AGAIN will I touch polyester for quilting.

I use Dream Queen poly batting mainly because cotton anything shrinks. If you pre-wash all fabric, AND batting it is great. I pre-wash to shrink my fabric, then use the Dream Queen poly batting because it won't shrink. I don't wash my quilt when finished because the fabric is all pre-washed, no smoke, no pets, and my quilt never lays on the floor because I quilt as you go. I will add some additional information while I am at it -- it is the pounding in the dryer that shrinks cotton, not the hot water in the washing machine. Learned this from sheep farmers where I used to live.

I have also used cotton/poly blends in quilts and they worked great and are still going strong. Never used 100% poly though so can't vouch for that.

I've been working with some donated poly/cotton lately and did not encounter any of the problems that have been posted. Kept my iron on a low enough setting.... pinned my sandwiches about every 4" ... the tops were poly cotton scrap pieces that had been donated.... then I pieced my batting with warm and natural cotton scraps.... then I used polyester fleece chunks that I had salvaged from previous backings...pieced them together.... http://www.quiltingboard.com/picture...t-t264309.html

PS... usually I use 100% quilt shop quality fabrics in my quilts but that doesn't mean that you can't use whats available or affordable if you don't have those

Using poly cotton in a quilt that will be used a lot is an invitation to trouble. The poly cuts the cotton the the quilt wear out really fast. Before I knew what I was doing I made a quilt with poly cotton, all the fabric was from the same line and at seam lines it rubbed holes in the quilt. For a wall hanging maybe.

Interesting comments. A lot of men' s dress shirts are made of cotton-poly blends.

The first place that shows wear is on the collar - as on the all cotton and wool shirtd.
