There are several Applique techniques in my challenge book “Exploring Textile Arts“ This is called Raw-Edge because the parts that are appliqued are not finished on the edges in any way. To do this, I used iron on facing to hold down the purple and green applique shapes, then caught the edges on the main piece with a decorative stitch. I did this before adding the batting and doing the quilting. So the additional quilting areas allow the swirl and points to puff up above the rest of the piece.
This happens to be an image I tend to doodle all the time (mostly when sitting through boring meetings) so I picked it for this series of experiments. I plan to do the other 5 types with this same design.. maybe even the same color combos if I can find the right scraps. This fits my 8×10″ book plans. This is very similar to the type of applique I usually do in my collages, but I usually finish the edges with a satin stitch.
