Some people don't like poly thread for quilting, so you might want to keep that in mind.

For my own quilts, I figure that fifty years from now, if the seams and quilting lines are the last things left of any quilt that I make and all that's left of the rest of it are shreds and faded fibers, it won't make any the tiniest difference to anyone on earth. I pray to God that I won't care about it, either. ;)
