Hi there! Loving this so far, and barely gotten started! My local art supply store didn't have the Legion Stonehenge Hot press in a pad, so instead I bought large sheets of Hot press paper >140 lb. I am wondering if the Legion Stonehenge Hot Press Aqua (it's tagged as watercolour paper and I'm not sure if this is maybe not smooth enough -- all the watercolour paper I have is quite nubby) is the correct one to get. This is available in pads from Amazon for a decent price. Could you advise? Thanks! Here's my colour reference!
