It has the softness of both fibres mixed into a smooth, light yarn that I think will be warm in winter and cool in summer. Should be great for wedding and party shawls. As cotton doesn't take acid dye in the same way as animal fibres, the cotton element has the potential to fade with time, rather like denim jeans.
Hope you like it - a few shades available now, with more to come later this month (when I've finished preparing for Bakewell Wool Gathering!). I see one of my Ravelry group members has snapped one up already - that was quick! She tells me it managed to just "fall" into her shopping cart - surprising how often that happens to some of us :)
