Plumemo Flow

Plan 🗺️ and measure 📐 book 📚 spines to size boards and stiffeners for hand bookbinding. Plumemo Flow helps hand bookbinders predict how thick a sewn text block will be, before the first stitch. Build 🔨 a block from its sewing structure, trim size, thread weight and a stack of signatures. For each signature you set the sheet count, the fold, the grain and the paper. The app 📱 predicts the spine thickness as sewn and as pressed. Once a block is sewn and pressed, record the spine at head, middle and tail. Plumemo Flow compares your readings with the prediction and shows how far the spine swells for each paper and thread pairing. The more blocks you measure 📐, the closer the next prediction gets. What you can do: - Keep a list 📋 of text blocks and filter 🎚️ them by status: planned, sewn, pressed or cased. - See 👀 predicted and measured spine thickness side by side, with spring-back after pressing. - Check ✅ whether a spine is even or wedged from head to tail. - Attach a spine photo 📸 taken against a scale. - Work out board width, board height and spine stiffener from the thickness, joint allowance and square. - Follow swell factors on a chart 📊, block by block, and open each paper and thread pairing to see 👀 its history ⏳. - Keep your own list 📋 of papers and threads, with weight, caliper and grain, and archive the ones you no longer use. Plumemo Flow starts with typical paper and thread values, so you can plan 🗺️ a first block right away.
