These were my first attempts at either and I'm pleased to say I think I caught on pretty quickly.
The ruffled edge on the pillow wasn't difficult once I got used to the speed I needed to work at.
The rectangle was my practice piece on the applique to learn how to pivot the corners. It took a few, but I got it in the end.
Then the heart was my second applique project.
It isn't perfect either, but I played (on one small section) with using the feeds versus not.
However, on it I was able to pivot in the points which is what I was testing.
My next adventures include learning to use the small rolled hem foot.
I tried and had no success, so it is off to YouTube to look for video guides.
