Never fill the bag more than half full. For color flow decorating, you need a flat, level and firm work surface. Color flow is softened by adding small amounts of water. Use grease-free utensils and bowls, as any trace of grease will cause the icing to break down. Paste food colors work best and do not affect icing consistency.
Colors fade slightly when a dried color flow piece is exposed to sunlight.
Outlines that are flat indicate soft icing or touching surface with tip while drawing outline. Remember, outlines are piped with the tip held above the surface to give a rounded line. Color Flow designs take a long time to dry, so they should be created at least 2-3 days in advance. Occasionally, color flow takes even longer to dry, and may not ever dry. This is almost always due to humidity.
