It's easier than you think to paint professional-looking, colorful geometric designs on fabric. If you can make a paper snowflake, you can paint a beautiful mandala design. This is a fun project for kids and adults alike.
Make a paper snowflake, cutting your design from freezer paper.
Place the paper snowflake, shiny side down, onto the fabric where you want your design to be. Carefully run a hot iron over the paper snowflake until the paper snowflake has adhered to the fabric. (Make sure no edges are loose.)
Paint around the edges of the snowflake with fabric paint. You'll also want to paint any holes in the paper with paint. For a colorful geometric design, I suggest alternating colors, filling all of the similarly shaped holes with the same color all the way around the design.
Once the paint has dried, carefully peel away the freezer paper.
To set the design, follow the directions on your particular fabric paint. In most cases, you'll need to cover the design with parchment paper and iron over it for a minute or 2.
Notes
To keep the paint from bleeding under the edges, use just enough paint on the brush and dab the areas that need painting. It's best to keep the brush in a vertical position so that you don't push the paint under the edges.
