There are two techniques you can use.
1. Mix equal parts of white acrylic paint with Soft Flake Snow™
2. Spread Flex Paste™ with a craft stick, then sprinkle with Soft Flake snow while wet.
The drying time of Flex Paste varies with thickness of application and environment. A thin layer will dry in approximately 30-40 minutes. Flex Paste should be applied no thicker than 1/16. Humid weather will extend the drying time. To speed up drying time, place a fan in the room
