Refrigerator curtain

I'm trying for more economy.
Wormer it is, easier the chilly air in a refrigerator is to escape.
The icebox electricity consumption makes up the grater part of my using.

How to make the curtain:
materials:
Hook and loof fastener with double-sided tape
(not much adhesive power between hook and loop. The adhesive power of double-faced tape gets weaker because of the chillness.)
PVC transparent sheet

1) Cut PVC sheet to fit into your box.
Width of it is just right. Length of it is longer than the length of the inside of the box. Leave some margin for sticking the fastner and for trimming.

2)Stick the fastener on the curtain and on the top of the inside of the refrigerator.
3)Slit it octopus-like straightly. Leave the margin part. The width of the leg is better to be about 5cm.
4)Stick the curtain on the inside of the box.




The cost of materials is approx. 400Yen.($3)
The cost of worm keeping sheet and bubble wrap is already recovered.

I believe I can recover the expenditure.
