1/2 sheet 300lb Hot Press – Recently I went to open some watercolor sheets that I bought at Cheap Joe's in NC about 2 years ago and realized they were Hot Press instead of Cold Press. Since I had invested so much money, I thought I would give it a try. The difference was amazing. The paint did not move over the surface but seemed to be soaked up by HP. I tried to wash in the sky and I couldn't get it to move and blend like I can on CP. I did notice that on the HP it was easier to make crisp shadow lines. I almost threw this one out about 3 times but I decided to keep trying. Let me know what you think.
