Review: No stretching required. - This paper is awesome and do require stretching. It is a pleasure to work with when lots of water is required.
Review: It’s *NOT* black paper thank goodness! - I first thought it was black paper and was super disappointed. but after a little examination I see it is white paper. I was trying to be positive and thought maybe I can try black paper. Started looking up videos on watercolor painting with black paper. No need. Lol. I’m so happy. I wrote the seller who is probably laughing at my Archie’s naïveté. This arrived quickly and I’m excited to use this high quality paper! Thank you. I will ask to amend my seller feedback.

## Questions & Answers

**Q: what is the larges sized block of 300 pound, cold pressed?**
A: I believe it is 10 X 14 inches.  That is the largest arches 300 lb watercolor BLOCK paper pad I’ve seen.

**Q: Can both sides of 300lb cold-pressed paper be used for Watercolor?**
A: Yes! Whatever side of paper of the paper you prefer. 300lb. Water color paper is quite heavy so less likely to buckle.

**Q: Is the block white or black?**
A: The block is white

**Q: How thick (NOT weight) is each sheet in inches or mm?**
A: This is 300 lb water color paper. It isn't measured in thickness, whether inches OR millimeters. It is just as thick (or just as thin) as all other 300 lb watercolor paper. The only way to tell how thick a sheet is would be to put a micrometer on it. All that said, it is not _very_ thick--perhaps about as thick as stiff poster board.
