Pi Day 2021 Grid Pattern

The first piece of my 2021 Pi Day Puzzle Stitch-a-long! This pattern is for the grid only; the patterns for each square will be revealed one-by-one once the stitch-a-long begins on March 14th!

This pattern-- and the rest of the stitch-a-long-- is completely free, so don't worry about Gumroad's price request! There is no need to donate, just hang out and enjoy the puzzles. :)
