When you purchase the "Pastel Set of 3," you will receive 5 high-resolution PNG files through a Google Drive link provided in a PDF. The designs come in various sizes, including 2:3 ratio, 3:4 ratio, 4:5 ratio, 11:14 ratio, and A series paper sizes. If you need a different size or would like to customize the colors, please contact me. You can print your designs at home, at a local print center, or through online services. For the best quality, I recommend using satin or matte finishes on heavyweight paper. For easy online ordering, consider using Gelato for a variety of wall art posters.
