There are always parts of quilting/specific projects that are not a favorite. I've mentioned before that pressing is not something I particularly love, but there is definitely something waaaaaaaay worse.
I hate it. I dread it. I've tried different methods, different rulers, etc, but the bottom line is that it has to get done one way or the other. No shortcuts. Just get it done, preferably in small batches.
At least the finished product is worth it!
