Another day, another plaid!
This single crochet intarsia block can be used as part of a multi-design project, or repeated and tiled for an amazing plaid throw! Colorwork blocks are stitched from the bottom up, then embellished with surface crochet.

Free pattern is on the blog, there are YouTube tutorials as well - one overview, one on neat color changes/invisible floats, and one on the surface crochet section. Links on the blog.
