I am a finalist in a big international design competition, and my entry was a yarn winder. I'm in the midst of putting together my second-round submission, which is a poster. I would really like to have a few quotes from prospective users/customers of such a product, so if you are a yarn person and feel so inclined, could you kindly tell me what you think of this product concept? Do let me know if you need more explanation than these pictures provide. Thank you!

EDIT: Some of you have asked for a video, which is of course perfectly logical. I don't actually have one, as this is a non-working model; it's just foam and paint and Photoshop at the moment. However, I'm including a video of a winder that has a very similar mechanism, although I didn't make it.
