Hi Campmuch,
Here is a twin electric blanket, and here is a heated throw. While short, the Heated Throw will keep your feet warm, to be sure.

This is something to keep in mind when buying a heated blanket:
If you have a MSW-Inverter you need to buy the old-style, rotary dial heated blanket, because all those digital display type heated blankets have been known to catch fire when you use an MSW-inverter! So that's not good!!!
If you have a PSW-Inverter then you buy either type of blanket!
