These thank-you notes can be printed on AVERY 3268 Note Cards (available at most office supply stores) for a polished looking card! Otherwise, you can print the cards on any 8.5"x11" paper and just cut and fold. The note cards fit in standard invitation-size (4 3/8" x 5 3/4") envelopes.
The note files include a second page with lines to make note writing easier—just print page one (cover), then flip and print side two (inside with lines)(see your printer's instructions for printing double-sided); or you may choose to only print the cover page.
