When it comes to Wrist Warmers, What do you think?

When it comes to wrist warmers, which style do you like best?  Do you like the fingerless glove or do you like wrist warmers in this style, without the hole for the thumb?  I'm getting ready for a show in December, and I want to feature a line of crocheted wrist warmers.  I use them from fall into late spring.  I know I'm not the only person in the world who has cold hands.  I think they have the potential of being good sellers.  If you were to buy wrist warmers, would you first choose the fingerless gloves or would you choose a style similar to the ones I show in the photo.  I'd love your feedback on this.  Thanks.
