Door curtains

My front door and side window unit is in a recess - just like an ordinary French/patio door arrangement, so we put up an 8 ft wooden curtain pole and a pair of old, lounge, lined curtains, This left a 6inch void and if the curtains were drawn, but not to meet, the door could be left open if necessary.

I have a glass door from the hall (not heated) into the living room and the glass is very cold, it’s not aesthetically pretty but I stick bubble wrap over the glass it seems to work. There’s only me in the house and I don’t care what it looks like.
