I, like Lisa , use the vintage sheets :O) when I can find them. I find them at gr sales too.
The ones I got at W-M were 200 thread count. only $4.00 for a twin flat size. That is a lot of material for the $$$. I hand quilt and don't find them hard to work with.
I am always thinking to thin of material wouldn't hold up.
PS I have been here a short time and have learned so much.
Been quilting for 15 years, but nothing real fancy.
Started with jeans quilts. So maybe that is why the 200 count cotton sheets didn't seem difficult.
