Hiya - so I think it's this one - www.amazon.co.uk/gp/product/B014FBZ2RK/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 - it's hard to know as I brought so may different ones, but this one says it's 200gsm and the one I used for this layout was super thick, so I think that's the one!! Just need to make sure to print using express mode or whatever your fast print option is so it uses minimal ink - that way it won't smudge :-) x
