I love using my Perfect Pearls but I hate that I can never get all the powder off in the areas I don't want it. After getting frustrated using a tiny brush and still not getting it clean I grabbed my canned air that I use to clean my keyboard and used it on my cardstock. It took off the exxcess powder and left a beautiful clean stamped image covered with the perfect pearls (see post below for cards I did this with). Then I just spray with fixative spray and allow to dry!
Hope this helps:)
