Appliqués are special because they are a fabric in their own right. It is fascinating to watch the machine make a web of threads that create an underlay for the design.
The appliqué can be made on a fabric backing or on a stabilizer that disolves. Once the design is complete the fun begins. You an create magnets or velcro tabs that allow you to change designs. Or you can permanently attach your design to an object of your choice. You can even use them in a collage or scrapbook.
Let your imagination be your guide!
