I found this dark wood effect adhesive sheet at Bunnings, so I covered the cardboard shelf with it.
It looks OK, and it made it a bit more durable.
Today I made another display thing for my stall.
A cardboard box with a hanging board on top!
I covered the box with the same wood effect sheet.
I used the craft board I got from craft shop for this sign board.
I can now hang my small bags here.
I tested it, and it works great!
All I need to do now is to make few more bags for the stall!
