I enjoy some 12"X12" painted dilute metal tiles that I want to attach to a alien textured wall. How do I do this? I am wanting to use 16 tiles, 8 that are 12X12 cork...

I am wanting to use 16 tiles, 8 that are 12X12 cork that I will hot glue stuff to and the other 8 are the thin metal which are alluring and dry erase. I would love to attach them in a bearing that will not damage the textured wall and also allow my daughter to switch them into different pattern for a 4X4 section on her wall. There is nought on the back to sway them with. How can I attach them to the wall?
A size problem?
Answers:    you want to allow your daughter to move them so I would use velcro attached to the back of each panel and to the wall itself

the textured wall may require a touch extra adhesive on the velcro strip though to hold it firmly contained by place

after your done with that you can delicately sand off the glue on the wall, prime and then paint
