Measure One Square, Plan the Whole Blanket
Every calculator here starts from something you measure, not an assumed gauge. Crochet a single square, block it, measure it, and the blanket calculator turns that number into the full plan: how many squares for a baby blanket, a throw, or a king-size spread, laid out in an across-by-down grid with the true finished dimensions. The yarn calculator works the same way for yardage — project size, stitch, and yarn weight in; yards, meters, and whole skeins out, with a safety margin so you never run out one row from the border.
Colors Are a Math Problem Too
The pattern generator shuffles round-by-round color combinations from curated yarn palettes and previews a whole blanket of them — because a square that looks good alone can turn muddy in a 10×12 grid. When a combination clicks, download the chart and take it to your project bag. All three tools share the same idea: do the arithmetic once, properly, and spend the hours on the hooking, not the second-guessing.
