Three panels that enlarge to dimensions with aspect ratios which are 7.75 x 23.75, or anything in between.  The pattern is sent with the patterns for the three panels (center one has the hummingbird) printable on a letter size paper, unless otherwise requested.  Enlargement will take this to above dimensions.  Also,  if you want, just ask for the large size pdf files, and take them to Staples or Kinko-FedEX to print.
