Puffy Tactile Soft Pink Embroidered Butterfly Patch/Applique Iron-On 2.25"
Puffy-soft and a bit squishy, dimensional, fun to touch because it's pink velvety soft mini-nap fleece (!) plus embroidered hearts and flowers. High quality appliqué from France is about 2-1/4" x 1-3/4" and not quite 1/4" thick. Iron-on, or for even more strength, stitch it.
Use the cotton setting on your iron, and a press cloth (or pillowcase) over the appliqué. When you iron, press down and hold for 30 seconds. Let it cool for a few minutes.
Flip your project over and do the same on the other side. Let cool for a few minutes again.
For an even stronger bond, stitch around the edges.
