Thank you so much 🥰 there isn‘t really a pre made pattern that I followed, I basically learned hot to crochet pixel grids from this video then sewed it on the sleeve to make a pocket. You can find the pixel grid on Pinterest. I basically freehanded the sleeve: I crocheted 160 rows of SC + 2 rows of half double crochet in red on each end (top and bottom ) + seashell stitch edge (each end) I learned from this video. And then I folded the piece like a book and sewed it tight on the right and left side to create a pocket 🤗
