Two Ikea Expedit bookshelves I bought off Craigslist- one needed repairs- but it was so cheap it was still under $70! The other was $120 or $140..read my old post here. One is art, the other is pleasure reading books.
My old pine armoire from my single days- has math games in it for now and my office supplies- I will changing this around probably.
My free spinet piano from Craigslist- in pristine condition. (This is my second piano off craigslist, I sold my first for a profit and then got this one free).
My large table my awesome crafty husband made for me after I showed him the $1000 table I wanted from the Pottery Barn- details on the creation of if in the old post.
My white board from Craigslist- around $60 I think.
A small free black book shelf (from this homes previous owner- actually her trash she just abandoned here) for the required booklist reading and file cabinet of our families important documents- non homeschool related. (We have a prayer shelf or altar there. I am learning this used to be called an oratory- I may not be saying it right, we have several family altars and prayer tables in our house)
A "circle time" area, our Papal flag and all our games and art supplies are contained in here. Plus the little kids table my mom saved and the tables and extra chairs.
I have Catholic decor all over from the Goodwill. I don't like paying full price for much- I blame my parents for my thriftiness- as we had 5 kids growing up and they were conservative with money if you know what I mean.
