Hi, sorry, We could not go this year, but we are planning to return in 2014! T-T
Hey Sharkybutt, probably best if you go check out one or two art materials shops or stationery shops and either try out anything that looks like it might work, or ask an assistant about really good opaque white inks or pens. I’ve used a variety of stuff over the years, and each one is good for it’s own thing, so get out and have an experiment :)
Many thanks for your soul.
