Hi BebopTalulah (great name!)
Bigbunniesuk's advice is great. Stick to straight lines and well-behaved fabric (such as cotton or poly-cotton) until you feel more confident.
The patchworkers and quilters might shoot me down for the advice I am about to offer, but I always find a rotary cutter and a ruler really helpful for when those squares don't quite match!
I don't do a lot of patchwork, but I do find it a very useful starting point with any new machine. I have my "guilt quilt" in pieces in a drawer, which I started when I got my last machine about seven years ago (hence the guilt!). One day I will get around to finishing it, but I know I will have to tidy up the squares before stitching if I want them all to line up!
I've also discovered crazy patchwork, which is great because it's all sewn in straight lines, but doesn't need to line up! The best of all worlds .
You will get the hang of it, and I am sure you will become highly accomplished since you have the most important qualities - passion and enjoyment! Just by indulging those, you will be building your experience and knowledge. Have a ball!
