Applique quilt size: 18" W x 15" H
Cut your background fabric to 19”x 16” first. This is the fabric you will put all of the other pieces on top of. Then cut and place the dove, heart and ribbon on top of the ombre.
Once your applique pieces are fused to the background, stitch with a straight stitch around each piece with matching thread.
Trim to square, then add a 2” border. Make the ombre strips border an opposite fade to the background.
Add batting and backing and quilt as desired.
Your local quilt shop is a great resource for fabrics and techniques.
