I posted my piece on Reddit for advice and I didn't realize that I had quite a noticeable seem running up one side of the table runner, but the wonderful members of r/crochet linked me some videos to help fix this problem in future projects. I haven't experienced such a welcoming and helpful community in... well... ever! It only fed my crochet fire and made me even more motivated to improve in this craft.
I have other updates to post about, but my hands are currently frozen from winter's fierce comeback today! See you next week!
