This is a really easy technique for making painted cards that look very professional! It is also my new favorite technique for combining digital design and painting: using the Silhouette digital paper cutter to cut vinyl stickers as paint masks on watercolor paper.
The results are extremely crisp. There is absolutely zero bleeding, even if you use a ton of water. It really surprised me how well the vinyl keeps out the watercolor.
You’ll need a digital paper cutter like the Silhouette, some watercolor paper and paints and some adhesive vinyl.
