What great organizing set. I would use them for my studio! At the retreat , I pack in a suit case with wheels, and leave by my table. I use 2 gallon Ziploc bags for my projects, I bring a few extras, and leave in my car. I have a clear 3 tier stacking storage case, this really works the best. I do not want nothing on my table but my project.
I also have a small basket with most used items like several extra machine needles, scissors, seam rippers, etc.
I usually attend 3 to 4 different retreats a year. Have fun.
