Insert your photo into the wax-filled mold. Fully submerge your photo and allow it to sit for a moment or two. It will soak up wax and displace any air that is within the paper.

If there are bubbles still sticking to the photo, try to move the photo around a bit to dislodge as many of the bubbles as possible (chopsticks are handy). Having no bubbles is ideal, but not always practical, so don’t waste too much time on this step.

Also, lightly tap the sides of your mold with a blunt instrument to free up any bubbles that may be lurking there.
