A paper piecing class/ demo. I use freezer paper instead of a tear away paper and find it to be much easier and less time involved, since you don't need to remove the paper. Maybe you could find someone to demo this procedure. Bobbin work or using different embroidery threads or textured threads in your machine. Couching threads- how to and demo. Adding piping or skinny flanges to your binding. Do a hands-on with fabric paints, Paintstiks, fabric markers. My Guild did a hands-on with rust dyeing. I missed that meeting, so I'm not sure how it all worked out, but do know that people went home with wet fabric, they had to rinse out at home the next day. My Guild has lots of long armers in it, maybe yours does too. Perhaps some of them would be able to share some ideas of how they decide what designs get quilted in different portions of a quilt. Binding, borders.
