I had no idea there were so many ways of "preparing" the paper so it doesn't buckle, this was super useful. I'll definitely try them out to see which one suits me better. Right now I'm not using watercolor paper; I asked for it in a couple of stores and they looked at me like I was an alien! I don't know if I'll be able to find it here in Venezuela. Maybe I'll have to buy it in Amazon.

For the moment, I have a block with paper sheets that are very thick, called "cartulina" in Spanish (not sure of the translation). So it holds the water good enough. I noticed that when I use the paper when it's still attached to the block, it doesn't deform, just a little bit in the parts where I apply too much water, but when it dries it doesn't look bad. However, if I take the paper off and do it in smaller pieces, it looks weird. I almost had an heart attack the first time that I weted the paper and it rolled up.

That day, I searched a bit and I learned about using tape to attach it to a surface and it's easier to work. I like it because it's a fast and effective way to avoid the paper to buckle. But I only do it if I'm not going to use the whole paper.
