"National Pig Day is an event held annually on March 1 in the United States to celebrate the pig. The holiday celebration was started in 1972 by sisters Ellen Stanley, a teacher in Lubbock, Texas, and Mary Lynne Rave of Beaufort, North Carolina.[1][2][3] According to Rave the purpose of National Pig Day is "to accord the pig its rightful, though generally unrecognized, place as one of man's most intellectual and domesticated animals."[2] The holiday is most often celebrated in the Midwest.[4]"
Here is a mini pig round-up, lol, so to speak.
I went a little nuts making the same amigurumi pig over and over again one year. Then I gave them to people on National Pig Day. Here is the free pattern for it from lionbrand. Here are 3 free pig patterns from lionbrand. The gift bag above was pink to begin with, then I added felt and large google eyes to turn it into a pig bag.
Since this isn't much of a round-up, here are the results of a google image search for pig crafts.
