Watercolor warps my paper!

You can find the sketchbooks on my page https://www.adreamoradayart.com/ You can find watercolor blocks and the boards in your local art supply store or online https://www.amazon.com/shop/influencer-99922a4c When working on loose paper, I highly recommend taping it down. I sell artist tape in the shop, and that's what I use. Your paper will still warp some as you paint, but don't panic, just let it dry and it will flatten out a lot! When painting in sketchbooks, look for watercolor paper. The heavier the paper, the less it will warp. The smaller the book, the less it will warp. Just know that changes in the paper are going to happen when you are applying a bunch of water and paint. You're not doing anything wrong!
