Here is a brief overview on how to use scrap magnet sheeting, a laser cutter and Corel draw to make magnetic poetry.
Magnet sheeting may be made of PVC and cutting it in this manner may produce small amounts of extremely toxic chlorine gas. I am not sure. You do this at your own risk.
Step 1: Go make your word file.
Measure your scrap magnetic sheeting.
Open Corel Draw and make a text block the size of your scrap magnetic sheeting. My scrap sheeting was 3.5" x 24" and as such I wrote enough semi-random words to fill that space.
The text should be of transparent fill with a 1 pixel black outline.
