As promised I mentioned that I would post the patterns to the tops and sweater I wore during the crochet retreat:

Free pattern -- Granny stitch hoodie cardigan I wore in white, black, grey and brown using Mandala Ombre yarn, free pattern (I added the pocket on my own): https://www.mamainastitch.com/riptide-granny-hoodie-crochet-pattern/

Ko Nelson, I found the tunisian crochet tank top pattern.

Friday during the day, found the pattern for the Tunisian tank top I wore, I used Lion brand comfy cotton in Grey (it's discontinued, it's 50% cotton, 50% acrylic blend). I modified the straps a bit and I did not add the bottom picot edging.  https://www.eandpcrochet.com/pattern-the-french-moss-top/
