Hi Pat...here's a topper / pillow cover i made to go with an inexpensive store bought comforter. It is 24 x 72 and on a queen bed, just to give you an idea of how it can look. [ATTACH=CONFIG]512445[/ATTACH]

Step back and punt! Say to yourself, "I am not making pillow cases. I am making pillows." Put a backing on your top, leave an opening large enough to get your pillow inside, hand stitch it shut and voila! You have a pillow. froggyintexas

I don't think that all those seams would feel good on you face when you lie down. Why not just make a runner (like a bed runner for the bottom of the bed) but make it for the top of your pillows. It would match and look great! That way you get the extra length for a minimal amount of work. Just put it on after you make the bed. Good luck!
