DIY Big Bang for Your Buck Wall Art. Using black foam core, Bits of Everything made a 20” by 60” (HUGE) wall picture collage for way under $20. Tutorial from Bits of Everything here. *I would not use Mod Podge, but that’s my personal aesthetic.
DIY Hipstamatic Constantly Changing Canvas Frame. Tutorial from Dyani at Craftster here. Clever idea for square photos - put velcro on frame and then on photos. With photos being so cheap these days, you can switch them out and change up your collage of photos.
