That link will display my photo attempting night-night method.

First i'm sorry because i failed to upload the photo here, i had to use 3rd party link.

Now from that photo, i want to ask for advices to make the success rate higher.

And i have some questions about it :
- Should i use a thicker cloth than that?
- Should i add more cable ties on different location to increase the pressure?

Thank you.
