Buying Guide

Choose the right texture

Stencil pastes and butter-like textures offer dimension without warping lightweight card stock; thicker metallic pastes give raised effects while fluid inks are better for washes

Check compatibility with paper

Select mediums labeled safe for paper or mixed-media; heavy-bodied acrylics may require thicker card stock or isolation layers to prevent curling

Prioritize lightfast and archival pigments

For cards meant to be kept, look for pigments and additives described as lightfast or archival to reduce fading over time

Consider finish and application method

Metallic and pearlescent pastes create reflective accents while matte texture pastes add tactile interest; choose based on whether you’ll stencil, palette knife, or brush

Evaluate kit value and versatility

Sets that include multiple finishes or coordinating colors increase creative options and can be more cost-effective for varied greeting-card projects
