Pi Day 21 Puzzle 7

In a series full of logical grid puzzles, there must always be a space left for the classic: the one and only official Logic Grid Puzzle™. Use logic and deductive reasoning to figure out what pattern each stitcher is working on-- and how they're making it, and with what.

This puzzle can be solved completely as either on paper or in the spreadsheet, and will have a bit of backstitching at the end. Don't open the key until you've solved everything, though!

Enjoy! :)

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. :)
