This is WAY, WAY fun! I'm listening to books on tape, sitting at my big bead tables, embroidering the centers of the hexie flowers on my Grandmother's Flower Garden quilt!!! The embroidery serves as both embellishment and quilting, although not all of the stitches go through all the layers.
Here's how one of the flowers looks. Of course you can see the basting stitches which hold the top, batting and back together while I quilt. I'm using a single strand of embroidery floss for each flower center. The longer spokes are just on the surface, while the center knot and short stamen (spokes) go through three layers, quilting them together. It looks fairly neat on the back.
Here's how a cluster of the flowers looks (click on picture to enlarge and see detail). As you can see, I'm matching the thread color (more or less) to the fabric color. At first I considered doing all the centers in various shades of yellow floss, but later decided I don't want the embroidery to be that obvious. Instead, I thought matching it to the fabric color would add a subtle detail, one that would only be noticed when viewing the quilt closely.
After finishing all the centers (estimate 60 hours), I'll begin to quilt around the flower petals with standard quilting stitches using a "harmonizing" color of 50 wt. thread.
