Sewed the top sheet to the bottom only at the foot.
I leave them on the foot of the Vee, rolled up. Takes about 45 seconds or so to make the bed. bout the same to put the linen away.
In cold weather I have a 100% wool blanket on top, and it gets rolled up with the sheets,to the foot. In cool, but not cold, I have a fleece blanket there instead. When not in use, the fleece lives in a throw pillow cover.
Here's one of the throws. Has a Mola from the San Blas sewn to the front
