When completing I breakdown, I will be speaking in terms of three different categories of items:

Purchased items (like it sounds)

DIY items (which I made, but purchased inexpensive or reasonably priced materials to do so)

"Salvaged" items (items that were free of charge, whether they were found on a curbside or in a friend's basement, Craig's list, or previously discarded, now repurposed items the client had)

Let's first address the living room:

Purchased items:

Two red pillows, purchased at TJ Maxx, at $10 each ($20)

Three pictured frames, purchased at Goodwill, at 99 cents ($2.97)

DIY items:

2 geometric prints on canvases I purchased for a total of $12 (already had the paints)

Salvaged items:

Zebra throw, which the client had but didn't use

2 glass and black iron end tables, kindly given to me by a friend

Ninja-style bandana, which the client had, now used as a coffee table runner

Coffee table books and magazines, which the client had

Eye pictures, made from an old poster the client had (with permission)

Now, onto the bookcase gallery wall:

And lastly, the bedroom/sleeping area of the studio:

Two throw pillows from Goodwill at $2.99 each ($5.98)

Minus tax, the grand total comes to…$148.54

Almost exactly $50 over, just as I predicted. Still not bad for an entire apartment makeover.

As a final send off (for today), see some additional pictures of Matt's apartment that more clearly exhibit the details.
