Thanks guys. I sell a wide variety of stuff, about 1,000 pieces per year. Its mostly fedex or USPS-able vintage car parts or antiques, but I have runs where I'll sell several fenders and hoods, or some freight type stuff like engines or insustrial equipment.
We use recycled materials as much as possible - I buy bulk styrofoam at auction for pennies/lb, Kraft paper from grainger, tape from Uline...The boxes get knocked down for easier storage, and I try to keep bulk supplies handy.
Most of the work can be done on a kitchen counter sized bench, with a large rolling cart or open floor space for the big items.
BUT...what I end up doing is painting myself into a corner. A new load comes in while I'm still lotting and listing the items from 2 months ago, and I just start stacking it everywhere.
Finally I've decided to set something permanent up, with a larger area for storing packing materials, and more shelving for staging inventory (new items to be photo'd and stored, items currently listed, etc).
But I don't want to lose a lot of floor space to shelving either...Will try to post some (embarrassing) pics of my mess to illustrate...
