More questions..

Sorry for posting so much ugh. But I have more questions. These are about handpaws.

I was on YouTube and I found this review video for Mischief Maker's creation of Roko. Roko showed the comparison of her handpaw and her actual hand. (And there's a drastic difference. Lots of space for comfort.) and then I found Growly's chart for measurements required for arm sleeves/ handpaws, such as width of knuckles and wrist to middle finger..etc. I don't know if Im making sense right now, but with that much space in Roko's paws, you don't have much mobility of your fingers? I did make toony paws once, and I couldn't move my finger that much? Like bending it. Or was it so that the paws wouldn't end up too small? Or should I just stick to the paws that are "normal." (Normal fingers, no short toony paws and fingers.)

EDIT: Also, I've seen some paws with elastic cuffs sewn on, what's the general purpose for that?

Here's the video of Roko's review.  She goes over her handpaws around the 2:00 mark. She shows the comparison at 2:50. (This is really an adorable suit.)
