Pi Day 21 Puzzle 2

The second puzzle in my Pi Day Puzzle Stitch-a-long! The time has come to do some drawing!

This puzzle has both a printable PDF version and a spreadsheet version (for if you'd rather type in your answers), and it can be completely solved in either one.

Once you've solved the puzzle, take a look at the backstitching key (also included) to add the finishing touches to the pattern-- don't look at it beforehand, though, it's a bit of a spoiler!

Happy stitching!

P.S. 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. :)
