To Start things off, I did not think of this but merely revised it to work with my needs (Original Post: Simple Material Holder )
So I liked the design in thee above post but wanted something thin enough to put on bowed thin material and just a bit sleeker.
The holder uses tha same magnets as the first but replaces the need for glue with 
veneer, it holds amazingly strong and looks nice with the acrylic I used, also I have yet to put glue on them cause the little tabs touching the sticky veneer are pretty solid. !
