Not sure why this would make a difference. Unless the sheet has a directional print, you can lay your quilt top on it either way.

I only use 100% cotton. I use new sheets up to 400 count. If it's much higher, it's difficult to quilt. 200-300 seem to work the best. If the sheets are from a thift shop, they have been laundered so many times that higher thread count ones seem to work just fine. Be sure to look for flannel sheets too!

I've used Ikea sheets and I'm not sure what the thread count was, but they worked great.

I find muslin sheets to be too coarse to use in a quilt. I've used mostly percale sheets (210 thread count). The higher thread counts are not always accurate. There's some cheating used to claim the higher thread counts. I have used some claimed to be 300 count in quilts. As others have noted, it's getting harder to find 100% cotton sheets. It's also hard to find individual sheets sold separately.

I didn't know this Nice to learn something new now and then. Thanks for the help.

Thanks for the info. Our quilting group at church buys twin sheets when they are on sale for $3.99 each. We tie the quilts. I am not sure what their thread count is but I am buying some tomorrow and will look.

The cheaper sheets from Walmart work fine. They have less threads per inch so they quilt nicely. They also wash well and are all cotton. Much cheaper than yardage!

I have used sheets, even for hand quilting, but it is not my first choice. Too high thread count is very difficult to handquilt. I don't know about machine quilting. Also, my concern with poly/cotton blend...is it more likely to pill? One reason I avoid sheets is they tend to have a problem with pilling. I wonder if polyester blends are more likely to do that.

I to have used sheets but I also find that Connecting Threads has some wonderful quilt back fabric 108 inches wide and if your quilt is shorter than 108 inches you only have to buy the width and this also saves money and Connecting Threads has very good fabric I am only buying what I need to finish UFO's as todays fabric prices are out of my budget but I do have a large stash happy quilting

I've got to ask a stupid question-------------what difference does it make which side it which? If it's a solid color or a non directional print, turn it the way that works best for you.
