Hi ladies...I am working on a HUGE quilt (to me anyway--I'm still new to this craft...it's a large Queen) and because I'm procrastinating the pinning up the sandwich part, I have decided to make 4 pillow shams out of the 4 large blocks I have left. My question is, is it "expected" to have the shams quilted too, or is it OK to just keep the sham single ply ie no sandwich and therefore no quilting...I've never made shams before and never really noticed if they're always quilted! What's USUALLY done??? Thank you in advance for any advice you experts can advise me with!
