I,ve seen that fabric before. Very unusual and I love it.
It's not about working fast. It,s about the end result and enjoying the process.
As Ploshkin said, many of us have been at it for longer than we care to remember. But I can still make a mess of something basic and some afternoons I wonder what on earth I've been doing as I've accomplished nothing.
Enjoy using the bag, looks great. And good luck in your new job.
