Fluid watercolor paper is crafted in small batches at excessively slow speeds allowing for finer control of quality. This slow approach produces a sheet of great strength that shares much of the working integrity of more expensive mould-made papers. The Easy-Blocks are blocks of 15 sheets of watercolor paper that are glued along two edges, holding the paper flat as you paint. When your painting is dry, slide a dull knife or letter opener in the open side under the top sheet. Release the glue along one edge and pull your painting free! Available in 16 different size blocks.
