Why is poly cotton suitable for quilting?

Many modern quilters think that poly cotton fabrics are suitable for quilting because they do not shrink as 100% cotton does, it launders very well, does not wrinkle, and is easy to work with. Many other quilters think that poly cotton fabrics are UNsuitable because they do not accept stitching in the same way as 100% cotton fabrics: thread tends to lie on the surface of poly cotton instead of sinking into a soft ditch. Some quilters do not like poly cotton's too-smooth texture, preferring the softly crinkled affect produced when 100% cotton is slightly shrunken.
