I am making a goal tracker where I print the tracker on a card paper size A3 and use clay magnets. I need a frame that would accommodate the card paper as well as the magnetic sheet i put behind the paper.
Need shop recommendations where I could find the magnetic sheet and the frame plus printing.
I ordered online and it kept getting delayed (1 month) and then I received the wrong order so I decided to go ahead and do it in person
