I’ve always loved large statement wall art and thankfully it’s quite cheap to create! Our local printing store (Officeworks) can print large prints for only $3-$6. The frames that I use are ones from our local Kmart, though you do have to cut the print down a few cm on either side.
Below are some of my other favourites at the moment. Most of the below are free (minus one or two).
