Arts and Witchcrafts is a crocheting puzzle from the Wizard's Hollow round of the 2020 MIT Mystery Hunt.

## Puzzle Elements

Flavortext - Whenever I think about joining stitches, it always seems to go in one ear and out the other…

A Stitch In Time - The puzzle is presented as a set of crochet instructions. It will eventually form into a cylinder, mostly consisting of double crochets with a number of clusters of other stitches in between.

Hint in Flavortext - Whenever I think about joining stitches, it always seems to go in one ear and out the other

Connect-the-Dots - Categorizing the clusters of other stitches by type and number, each type of stitch turns out to have one cluster each of sizes 1 to N for some integer N. Connecting these clusters in sequence through the inside of the hat...

Indexing - ...reveals a number, which can be used to index into the name of the corresponding stitch.

Reordering - The clusters of size 1 are all at the base of the hat and equidistant from each other. Ordering using these clusters, starting at the single crochet, reveals the answer.
