I had some large pieces of upholstery fabric and purchased some more from the 50% off sale table, along with some quilt batting and made "quilts" for the doors. They are rather heavy, but they are stopping the drafts.
I sewed tabs at the top to easily slide along the rod, so the door can be opened without catching on the "quilt". This one is in the living room, and adds some life to a dark area.
This one is in the dining room. I made them long enough to "puddle" on the floor to stop the drafts. They add a cozy feel to the rooms. Hopefully they will cut down on the electric bill too.
Finally! I finally made them now that winter is soon to be gone. That's OK. I'm ready for next year.
Hope you are staying warm.
