PortaPuzzle Jigsaw Storage

[mikebarden@yahoo.com]

I have the 1000 piece Portapuzzle - does anyone else find these don't really do the job.
I can start the edges of a jigsaw and then place it in the Portapuzzle , stand that against the wall and when I open it again its all slid down - useless really ?

I wanted to complain to the manufacturer and cannot find who to complain to

I have tried padding out the holder with cardboard and it still slid down

I cannot see the point if the portapuzzle cannot be stood up and has to be laid flat for storing !

Any ideas that you have used to solve this

You can but grip matting online, or even at some supermarkets. Not that expensive, and might help.
