The main difficulty of crocheting this case is the using yarn – it’s fluffy and it’s hard to see where to insert the hook, it’s difficult to count the stitches. Therefore, I recommend counting the stitches in the crocheting process.
I crochet tightly, so if you get a loose case, then you can reduce the number of stitches in both the cap and the case, or take a smaller hook. The tighter the case will be, the better. So the Christmas tree will be fluffier, and the bottle will not be visible.
