AAAAAAAHAHAHAHAHAHAHAHA!!!!!!! OH, the memories that question brings back!
When I first started, we had a few little bars to play with. We had floor to ceiling bookshelves, 4 of them in the living room 3 in our bedroom (yes, we read a lot)
When I started, we used one shelf in the living room. that became 3, which became one of the full Floor to Ceiling shelves, eventually ALL the shelves. we bought a house that was split level, a living room and a small downstairs den. we spent our family time in the den, so we had a little tikes playhouse in the living room along with other toys. eventually, that was moved upstairs. the two daughters decided they wanted to share a bedroom and use the second room for a playroom. the little tikes went to the playroom.
then, I set up the two enourmous tanks in the living room. made cinderblock stands for them and had the 200 gallon Nalgene lye tank and the 200 gallon Stainless Steel soap tank in the living room.
By then, all the books had been removed from the bookshelves. on the floor were stacks of shipping boxes, sti;l flat for sending orders and all the other supplies I needed.
as for setting the soap to dry after cutting, that took the bookshelves in the living room. then the ones in our bedroom, in the dining room, and the den. eventually, the only room that wasn't used for soap in SOME way was the children's bedroom.
that's why, when we moved to Chattanooga, we decided the business needed commercial space. it had outgrown the house and it was either going to grow or die in the next couple of years.
the shelves we eventually had (and you can see them behind my family in the old pictures) were purchased at a going out of business sale. they were display shelves, very sturdy, easy to set up and break down as well as configure.
