Black Magnetic Powder- this type of powder is best for surfaces like tile, windows, or any textured substance. This powder is not ideal or substances like paper or any porous substance.
Step 1: Leave/find a print :) Step 2: Stick the brush into the cup of powder, make sure the powder sticks to the brush, as shown in this example.
Step 3: Gently hover over the print, moving in a circular motion, without applying too much pressure. The print should start to appear. Once the print appears, stop brushing over it, or it may get ruined.
Step 4: Take a piece of tape and stick it on top of the print. Make sure to rub over top of it to ensure that the print will be lifted properly. Slowly peel the tape off. There is your final product :)
