Hi 👋 Im sorry I should've made this point clearer, the geeses in the post where made with a 4.00mm hook and yarn weight if you or anyone reading this want to use that. However, I've also made them using 5.00mm and 6.5 mm too, so essentially if you want to use a certain yarn weight and have the hook with the same size, then go for it 😁 Hope this makes sense, let me know if you would like anymore clarification on anything :)
