I learned a valuable tip today from a fellow quilter and wanted to share.
I had always heard that using 100% cotton thread was best when quilting but never asked why. I learned today that using polyester threads with 100% cotton fabrics could actually tear your fabric since it is stronger than the fabric itself!
Now the only other problem is finding 100% cotton thread these days it seems. I have discovered that Coats & Clark threads are no longer being sold at any of my local retail stores and they are actually changing their thread fiber contents as well.
I hope you find this tip helpful. Quilting is such a time consuming craft/art, it would be terrible to ruin an heirloom because we used the wrong thread.
