I used a cookie cutter to trace the heart shape... that's actually a bit easier than other shapes because the lines don't have to be exactly straight, and asymmetry isn't as noticeable.
The spiral was fun to try, if not spectacularly executed.
It's coming together slowly but surely. I'm a bit concerned about how I'm going to do the squares towards the middle of the quilt, I need to really be able to maneuver the fabric and it's hard to do that if there's a whole bunch of it crammed up against the neck of the machine... and it's also hard to do if half the weight of the quilt is hanging off the side of the table.
So far I've managed to quilt close approximations of the following shapes:
a maple leaf.
I've also done some squiggles and zig-zags. Can you suggest any other shapes for me to use? I've got like 30 squares to fill, and I don't want to do too many repeats.
