This is something I came across last year and fell in love! They're called Smittens & I've been thinking about making them, but just haven't gotten to it. It's so you can hold hands while going for a cold walk outside! What a WONDERFUL Valentine's Day present. You can get these exact ones here.
Or you can go a little more handmade here at LoveDriven on Etsy. There are lots of different kinds she has on her site, but I like these the best.
