A4 sized, professionally printed onto 400gsm silky warm-white paper. The print is also soft-touch laminated on the front, which gives the card a velvety feel whilst simultaneously adding a little more protection to the image in case you use washi tape to hang it up! If frames are more your style, I would recommend IKEA for inexpensive A4 size frames (or A3 with a mount board for more drama). or charity shops to find more ornate/unique frames.
