Embossed Vintage Halloween Lab Charts Print and cut out a vintage lab chart. Rub an anti-static pad over the chart. Trace details you want highlighted with an embossing pen. Pour embossing powder over ink - shake it off on to an extra sheet of paper to save it! Add another color by repeating the process. Hold heat gun tool about 6’’ away from paper. The powder will melt and become shiny. Complete the lab chart by adding dowels and twine.
