Hi Haleema, thanks so much for reaching out and sorry for the confusion. Unfortunately this is one of my earlier patterns so I don’t have photos for it (I normally do!). What I mean by this is just to squash the arm flat and then secure it by sewing. I also use an alternative method sometimes of crocheting across the opening to make it flat. You can see that technique in action in this bunny pattern: https://littleworldofwhimsy.com/yuki-the-snow-bunny-free-crochet-pattern/.

Let me know if this helps!
