I'm being lazy with designing and sewing right now (in the middle of transferring apartment units in our building at the moment and therefore, packing) but I have been playing with designing rooms on 3DRoomstyler!
It's a program that I have had downloaded for a long while, played with a little and now after almost a year later, I am addicted! It's a free Chrome extension so anyone can download and play with it.
I will have an upcoming "how to" on it via another place I write, The Art Shake so mark your calendars for April 19th to get a basic run-down for how to make a room in it. (Or just try it yourself. It's pretty easy!)
For now, have a look at the rooms I very recently have made/designed in it!
"Oak Park Entryway"
"Chicago Front Room"
"Fictional Chicago Apartment"
