@Lilly I think a lot of people get the hats from innocent smoothie bottles around November December time when they have a promotion with age uk. But they are easy enough to knit/crochet yourself.Oh wow, that is just so adorable. Where do you UKers get these hats small enough for piggies?
If only I could knit or crochet! It seems that I'll just have to drool over UK piggies in hats.
