Print at Home
If you opt to print with your home printer, you'll need the 8.5x11 PDF file with 2 set up on a page that will be included in your download. You'll need to cut them out yourself. You can also buy the pre-cut 4x6 / 5x7 cardstock or photo paper if you want to print them individually.
If you are looking for a paper to purchase in an office supply store to print on, you should look for a heavy weight (we like a minimum of 100 lb. but some 90 or 80 lb options available in stores are a nice weight, too) and photo-quality brand. HP, Avery and Neenah all offer nice quality cardstock and/or photo paper. You can find these at office supply stores such as Office Max or Office Depot.
Tip: Be sure to pay attention to the printer type that's indicated on the packaging - inkjet or laser - and choose whichever type of printer you have. You would not want to print on laser paper with an inkjet printer.
