My new favorite tool in the sewing room is the humble Post-it note. When making the First Communion dress, I did a lot of samples to figure out what stitch settings or seam allowances would work best for various parts of the dress. In this case, I had to experiment with the blind stitch on my machine in order to get the most invisible hem possible.
But now that I'm middle aged, I have a brain like a sieve. So I carefully wrote the settings on a Post-it and stuck it to a corner of my sewing machine table so that when I finally got to the hem, I'd remember the stitch width that had worked best.
(By the way, the little pin cup in the corner is a feature of the Sew-Ezi table which I bought last January. I'm always careful not to sew over pins, and I find it so handy to drop the pins into that little indentation. It's much easier than trying to shove them into a pincushion.
