Shawna had to decorate 3 gift packages with ribbon. She used 13 yards of ribbon for the first package, 12 yards of ribbon for the second package, and 1 yards to decorate the third package. Shawna had 33 yards of ribbon left over. How much ribbon did she start with?
Shawna used a total of 13 + 12 + 1 = <<13+12+1=26>>26 yards of ribbon to decorate the gift packages.
Therefore, Shawna started with 26 + 33 = <<26+33=59>>59 yards of ribbon. Answer: \boxed{59}.
