The busy season will be so much more tolerable and productive if you give the shop a morale-boosting cleanup before things become hectic. I know that there’s never a good time to do this kind of thing but making time is really not all that difficult. One way to do it is to down tools for a day while things are still a bit slow and have everyone do nothing but clean up and reorganize. Reward them with coffee and donuts in the morning, pizza at lunch time and perhaps a beer or two when the job is done. Friday would be a good day because that will mean that paint (floors, shelves etc) will have the weekend to dry properly.
Imagine a busy season when you can lay your hands on materials and tools without having to look for them. Ink, emulsions etc. properly labeled and shelved. Clear walkways and work spaces. Clean equipment. Annoying minor equipment malfunctions fixed. Planned workflow.
A clean, organized shop is a happy, productive shop, especially in the busy summer season when there’s enough pressure without also wasting time because of filth, disorganization, and malfunctioning equipment.
