Artist Trading Cards (ATCs) are tiny canvases (2.5 x 3.5 in.) perfect for experimenting and trading. Use sturdy cardstock or watercolor paper, a few paints or pens, collage bits, scissors, and glue. Begin with a color wash or texture, add a focal (bird, owl, or village), then embellish with ink, stamps, or patterned paper. Keep designs bold and simple. On the back note your name, title, date, materials, sign, and trade to connect. For step-by-step photos, mixed-media tips, themes, supplies, and swap ideas, read our blog post!
