Here's the story.</p> <h2> The Problem </h2> <p>When I started amigurumi, I kept hitting the same wall:</p> <ul> <li>"Will this pattern work for my yarn?"</li> <li>"How much yarn do I really need?"</li> <li>"What's the right hook size?"</li> </ul> <p>I searched for solutions but most tools were broken or asked for signups.</p> <h2> What I Built </h2> <p>A complete set of free tools at <a href="https://aeternacraft.com" rel="noopener noreferrer">aeternacraft.com</a>:</p> <h3> 1. <a href="https://aeternacraft.com/tools/amigurumi-calculator/" rel="noopener noreferrer">Amigurumi Sizing Calculator</a> ⭐ </h3> <p>Scale any pattern up or down. Input your gauge and desired size, get exact yarn and stitch counts.</p> <p><strong>Why it's different:</strong> Unlike other calculators that just scale linearly, this uses <strong>cubic volume math</strong> — the way real crochet behaves.</p> <h3> 2. <a href="https://aeternacraft.com/tools/yarn-converter/" rel="noopener noreferrer">Yarn Weight Converter</a> </h3> <p>Convert between yarn weights (lace, fingering, DK, worsted, etc.) and find equivalent yarns.</p> <h3> 3. <a href="https://aeternacraft.com/tools/hook-size-chart/" rel="noopener noreferrer">Hook Size Chart</a> </h3> <p>Convert hook sizes across US, UK, and metric systems. Includes size comparison visuals.</p> <h2> How This Helped Me </h2> <p>I used these tools to:</p> <ul> <li>Resize my <a href="https://aeternacraft.com/tools/amigurumi-calculator/" rel="noopener noreferrer">Totoro Night Light</a> from 10cm to 30cm</li> <li>Convert yarn recommendations from US patterns to UK standards</li> <li>Find the perfect hook size for my favorite worsted weight yarn</li> </ul> <h2> Try Them Free </h2> <p>All tools are 100% free, no signup required. Just visit <a href="https://aeternacraft.com/tools" rel="noopener noreferrer">aeternacraft.com/tools</a>.</p> <p>Questions?
