The July Free Motion Quilt Challenge (Sew Cal Gal blog) instructor is Angela Walters. She is a long arm quilter but her background fill design called Tiles translates to the home sewing machine very nicely. This is a great little blank space fill design that can still be used with simple stippling or other background fill designs. It shows better on a plain fabric and is much more difficult to see on a printed fabric but that is the case with many quilting designs. The tile effect can be done with box type tiling or with angled lines giving a more jagged appearance (see the right upper corner of my sample) There is a picture of a quilt quilted with the angled line tiles on the tutorial, it looks very good with modern fabrics.
