I never put away my vinyl until everything is successfully weeded and masked.
If going out on an install, and I have the extra material, I will either cut an extra set or just bring the material.
Everything will go fine then.
But if I only take what I need, I know damn well I will screw up a letter, usually while the customer watches.
I always carry a small tape measure in my purse because I am paranoid about not having one, and if I don't have one that's the time I really needed it and substituted a dollar bill (if I had one) to measure something.
There are a few items in my painting kit that I probably haven't used in over 10 years, but if I didn't leave them in there I'd need them.
I also have some pounce patterns nearly 25 years old.
Not sure is it's superstition or Murphy's Law.
Love....Jill
