You might try "Quilt as you go" QAYG. Just google it or there might be a tutorial over in the Tutorial section of this form.
I like the idea of large floral fabric and practice outlining the flowers.
There's a website where a lady did 365 days of free motion quilting on a regular machine. Maybe someone on here can post the site.
Don't be afraid to try something new.
I can't remember if I saw it on Fons and Porter or read about it in one of their magazines. They took freezer paper and folded it in quarters, then eights, and cut a design, similar to making snowflakes. Keep it simple. Then they would iron it onto the fabric (shiny side down) and it would lightly stick to the fabric, then free motion quilt around the design.
One of the most important thing to learn about machine quilting is pulling the bobbin thread up to the top. This keeps it from getting tangled on the bottom and creating a mess. If you don't know how to do it, get someone to show you. I don't know if there is a video on line or not.
And remember, it does not have to be complicated to be beautiful.
