Place the snowflake with the still wet Mod Podge into a bag of flock. If you have leftover from other projects you might want to just toss your snowflakes in the bag the material came in. If you have other projects in mind, you might want to transfer some flock to a large zipper bag. Carefully move the snowflake around in the flock until all of the adhesive is covered. Lay the snowflake newly flocked side up.
