Thank you for checking out my art! I have designed and carved the stamps for these cards, and after hand printing each piece, fill in each print with watercolors. Every card is unique and what you see in the images may not be the cards that are sent to you. Depending on how many are ordered, I may need to create them on demand. But I'll have a handful in stock, ready to go! Some details: Rough measurements per card- About 3.75-4 inches × 4.5-5.25 inches. Depending on the cardstock I use, the measurements are unique. Materials - watercolor paper, watercolor paint, cardstock, ink, envelopes Each set comes with 4 unique hand crafted blank cards and 4 envelopes
