I love your pattern and the colors. Bargello is one of my favorites because there are so many variations. Years ago Olfa made a razor seam ripper that was only about 3/8" wide and when the razor became dull you just broke it off and another razor was pushed up in place. I now buy mine at Home Depot or Lowe's and my latest one was made by Kobalt. They're much cheaper than the Olfa version and seam ripping is a breeze.
