Fun technique I found on the After Midnight Art Ranch blog, watch the video here. Great way to use up scraps if you have them.
Cut up variety of colors on a craft sheet and sprinkle small amount of Opals Franklin over them. Lay another craft sheet (or parchment sheet) on top and press a hot dry iron over them for a few seconds.
If there are any holes, cover with more scraps, replace craft sheet and iron again.
Here's the same piece in the window. Fun!
Think I need to buy more colors.
