I use some questionable content fabric for the clothesline baskets. Some poly/cottons work fine in thread catchers, aprons, mug rugs etc. I have used them in quilts, I just make sure that I don't mix different fabric contents. You could mix them but they shrink, fade and iron differently.

It depends on what the poly to cotton ratio is... if its 30 percent poly I will use it in quilting .... if its 70 percent poly its a garment only or home dec . .. as I am really obessed with pressing and LOTS of steam when it comes to quilting... and high poly content does not lend itself to that kind of treatment.
Sometimes there are great prints that have some poly ... and I just can not resist.
I reciently saw a quilt made from all poly /cotton blends it was fabulous and you would not know by looking at it that it had blends.

Curtains, clothing, pillows, etc

I use it to make pillowases with...its soft and doesnt wrinkle much!

Put up your poly/cotton for sale. There are lots of us who sew for grandchildren and others as well as quilts. If the designs, colors and prices are right we'd rather buy from you than from Hancock's or JoAnne's.

What if you aren't sure if it is a poly blend or not? I am a fairly new sewer and need an easy way to tell.

I use poly cotton for whatever strikes my fancy. I don't follow rules easily!

I don't buy the blends. But then, I sew quilts, not clothes too~

I use, and recommend the use of poly/cotton for Project Linus and other charity quilts, the reason? Because of their being what they are they undergo such much more washing and laundering than normal quilts, sometimes every day, and poly/cotton is manufactured just for that, multi laundering.

For us die hard quilters it may seem wrong but remember these are not "Heritage" quilt they are "Huggles" for a poorly kiddie-wink and do a super job.

I have from being given or people sold them as 100% cotton to me. I am not sure what to do with it except maybe utility quilts? Maybe DD 14 can use her floor loom to make utility rugs but even for that 100% cotton is preffered.
