I finally decided to do something about it when our next winter power bill came.
Step 1: Electrical Outlet Insulation Materials
Step 2: Window Insulation Materials
Step 3: Door Draft Materials
I picked up this backer rod at a local store call Hardware Sales. It comes in various diameters up to 1. If you have a larger gap under your door, you could probably buy pipe insulation foam. Under materials there is a simple calculation to finger out how much material and backer rod you will need to complete this project.
Materials that you will need to complete this project:
+ 5' x 1dia. Backer Rod ( door widths x 2 x #number of doors = _Ft)
+ 11" x 33" Slippery Fabric ( circumference of foam tube + _ door width x 2) + 1" seam allowance = x # of doors = )
+ Thread to match fabric
+ Sewing machine (you could probably hand sew it if you wanted to)
+ Needles to pin material
+ Ruler and Tape measure to measure and cut fabric
+ Chalk pencil to mark fabric without leaving permanent marks
