I have had a number of people ask me how I get the "feathery" look on the edge of my acrylic projects. I use the Adirondack paint dabbers (think bingo dabber, with acrylic paint inside) and "scratch" the paint along the edge of the panel or shape.
It's hard to show this visually with just a photo, so I made a quick line art diagram. Laugh if you feel the need. I did. :)
The big "NO!" means don't go parallel to the edge, just following the shape of the panel. You want to "scratch" perpendicular along the edge.
Here is what I was working on while demonstrating this technique:
These are the new Clear Scraps Minis, which are small, 6-page albums that are three inches or smaller. This on is a cupcake shape, but they come in arrows, hearts and more. There are several different shapes and I will have them available for sale at the Orange County Scrapbook Expo Feb. 13-15.
