Plant C2C CAL – C2C Mum Afghan Square Free Crochet Pattern

[Image description] the C2C Mum Afghan Square lays flat on a wood-grain background with 4 skeins of yarn laying on the left side and bottom corner of the square.

Ah, the sun is setting on September and while I’m glad to have October here (my favorite time of year) I will miss this pre-Halloween month. *sighs wistfully* But, you know what the end of the month means, it’s a brand new square for the 2021 C2C Plants CAL! And this month’s new square is perfect for September and if you love a good 8 bit video game, the C2C Mum Afghan Square.
So, this is lucky square number 9! Have you been following along the whole CAL? If you haven’t that’s fine, these posts are here and the graphs are free for you to find and enjoy no matter the time of year. But if you have I hope you’re looking at your previous 8 squares with glee, like me, because it’s almost done! I haven’t decide how I want to add more squares but at this point I’m definitely going to be adding more squares to make it a larger blanket. Perhaps I’ll add some stash busting greens and browns. Ooh, or maybe oranges too. And purples! Ok, ok getting over-whelmed with ideas but I do have a pretty good idea on what cute little additions I could make to checkerboard the finished blanket with plain squares. But that’s future Amber’s problems (probably last week of December rushing to get this year-long CAL done Amber for sure).
I actually kind of love this square. It make me want to make a whole sweater with these cute little flowers, like my Sally Skulls Pullover or something. I mean, who wouldn’t love this cute little face? And think of all the colors you could make the flowers in! It would be so, so pretty. Ok, ok… I’m getting way ahead of myself here. I’ll try to file that idea away for another time, ya know? But I still do love this square because to make sure you have lots of time with them, you want to plant or crochet your mums in September. Or at least that’s what I read on the internet, so don’t quote me on it (except for the crocheting part, you should totally do that).
Anyway, I hope you enjoy this weeks square! It’s a fun one for sure and
Check out last year’s 2020’s C2C Coffee CAL, 2019’s Coffee Tapestry Squares, and the 2018’s Tapestry Afghan Squares.

I hope you all are healthy and happy and like this new design. Please be kind to one and other, wear your masks, wash your hands, and be safe friends!

Please note: I was provided the yarn for this pattern by Lion Brand Yarn for the purposes of making this design, without compensation. I wasn’t provided the yarn with the expectations of positive or negative reviews but I did enjoy using this yarn, I’ve used it many times and it’s always a great worsted acrylic yarn.

What was your question? Because this is a corner to corner pattern, which is worked on a bias. It's just like the Be Kind Wall-Hanging you commented on a few days ago. There are links in the notes if you are unfamiliar with the technique.
