This is a great project for a beginning sewer. The tricky part is bringing the finished edges into the middle. I lay a small ruler on my ironing board and folder over 1 1/2". You could also fold and press and fold to the press line. Good luck. These are fun!
Oh - the other tricky part is remembering to change feet when you go to straight to zigzag stitches! Had that issue on the first one. After that I chain sewed them and it was much easier. Did have my "Purple Thang" to push the fabric under the foot at the center.
