I love to have the embroidery machine just "clicking away" while I am sewing on another machine...piecing, quilting, making tote bags, raggy quilts, gifts. I would really miss my embroidery machine if I didn't have it...heaven forbid.
I too have embroidered out quilt blocks such as 2 fishing quilts I made for my youngest son & grandson...both were different, yet similar. They were really a lot of fun to make them.
Go to some LQS and get demos, ideas, and see if they have classes, etc. There's lots of ideas, tutorials, etc. on boards like this now, and gobs of info on the internet.
Good luck and have fun!
