lol, I was just going to post the same thing. Heart of the Matter does a blog hop every August and oen week is devoted to pictures of HS spaces. They're going to do it again this year.
I have my business (with its inventory and supplies) in a separate room from our homeschool room. Since I deal largely in fabric, I think having my (fairly young) kids using markers and scissors in the same room as my business would be a terrible, terrible idea. That said, if I WERE to combine them, I'd just get a LOT of good storage shelves and bins.
I do not use fancy bins, i use the smaller size clear Rubbermaid (or similar) bins, in shoebox and 15 qt size. I currently use a combination of some cheapish self-assembly modular shelves along with giant sets of metal shelves from Costco. The taller the better, because otherwise you're wasting all that vertical space that the kids can't reach, lol.
