I've learned to leave the sleeping bag at home. My sleeping gear is a
Thermarest, covered with a "sock" I custom made from an old sheet. Kelly
has the identical set-up, and we bring two top sheets and two lightweight
fleece blankets to go over us. This is a lightweight set-up and allows us
to add or subtract layers to suit the conditions. Also, it eliminates the
bother of a sleeping bag. I flip and flop several times a night, and find a
sleeping bag confining.

Open the sleeping bag up and us it as a blanket.
Sleep on top of it to keep from sticking to the pad.
Your sheet sounds like a youth hostel sleeping sack.
I have a polyester one that adds 10-degrees F of warmth to the sleeping
bag.
