I made these canvases using decoupage technique, glue gun and acrylic colors.
This is how I made them:
1. I carefully picked napkins that match.
2. I marked lines
3. I used a glue gun to make 3D effect on the lines.
4. I applied the napkins on the canvas using a decoupage lacquer.
5. At the end I painted the space between the napkins.
